There are really two things in focus when discussing this topic, one of which is almost always not considered by those who claim a loss of salvation. One of these is salvation itself and it is known as a recreation, or purchasing by Another, and a sealing until the day we are redeemed, which bodily hasn't happened yet, which implies the sealing persists. The other deals with the loss of reward or standing, which is where we see things in the parables where people are assigned a portion or reward of the unbelievers, which means they get nothing in the end, and Paul describes the condition as those who will have everything burned up, but they themselves will be saved. I do notice a lot of crossover between these two areas by those want to hang on to salvation loss, by mixing the two areas when it suits their need.
However, I have never seen the verses which show another recreation of us by God for those who 'walk away'. It's put across as some as act we do, but it would require a simultaneous act by God as well to recreate us back to our former selves. I've also never seen the verses that show since God purchased us and we no longer belong to ourselves, how we can successfully purchase ourselves back from God to give us the right and ability to walk away, and what price would be acceptable to Him that would supersede the blood of Jesus, or the verses that show how to undo a sealing by the Spirit in 3 easy steps.
There's just too many holes in that whole 'loss of salvation' theory.
Those don't seem to be so much holes as you are reading philosophical speculations into terms and circumstances which aren't necessarily implied or demanded by scripture.
First:
The seal of the Holy Spirit doesn't require that we will necessarily continue in faith. That isn't a connotation 'seal' has. For example, the seal on Jesus' tomb didn't literally seal him in or prevent Jesus from leaving- it showed the authority of Rome over anyone who would dare tamper with the seal. In a similar fashion, the seal of the Holy Spirit is God's guarantee that He will uphold His promises and His seal of authority over anyone who would try to snatch someone in the covenant away. But the seal doesn't prevent a person from exiting that contract by rejecting faith - and subsequently rejecting any claim to the promises he would have had had he remained.

Second: While a few verses reference a loss of reward or standing due to lack of works or sin, etc. there are many passages which clearly describe someone who does not continue in faith or remain in Christ as being cut out of the body of Christ and being destroyed, or with a final state worse than their pre-faith state of unbelief, or having no more sacrifice for sins, or being condemned, etc. (Rom 11:10-22, Jn 15:5-6, etc.) These cannot all be lumped together as many are explicitly clear that for a person to reject Christ after once believing will lead to themselves being denied before the Father.

Third: 'Re-creation' is a nonsensical phrase to apply to someone who returns to a former state or goes back to something he was once involved in, and so not finding it from scripture isn't just an argument from silence but is illogical. When we physically die God doesn't 're-create' us into dust - we decompose or are burned and 'return' to dust. Likewise someone who once had faith and rejected it is not 're-created' into their former state but rather 'returns' to it. The indwelling Spirit departs since they are not a believer, and without the Spirit they cannot continue in life with Christ. Hosea's wife wasn't 'recreated' into a prostitute when she returned to her old ways. A freed slave is not 're-created' into a slave if he returns to an old master. When God removed the priesthood he promised to Levi's descendents from Eli's family, they were not 're-created' into non-priests. A dirty person who washes is not recreated into a dirty person when they return to the mud. Fruit that ripens isn't 'recreated' into non-fruit when it later rots. Etc.
Scripture uses terms like 'twice dead (Jude 1:12),' 'return/again entangled (II Pet 2:20-22)' etc. to describe these people.
4th: Redemption doesn't stop us from rejecting God or ceasing to trust Him. How many times did Israel turn away and reject God, despite that they were the nation God redeemed? But more importantly, we only can have Christ's redemption if we have
faith.
"The law is not based on faith; on the contrary, it says, “The person who does these things will live by them.” Christ redeemed us from the curse of the law by becoming a curse for us, for it is written: “Cursed is everyone who is hung on a pole.” He redeemed us in order that the blessing given to Abraham might come to the Gentiles through Christ Jesus, so that by faith we might receive the promise of the Spirit." Gal 3:11-14
If we reject that faith, then we return to being under the law and hence return to condemnation.
"For he has rescued us from the dominion of darkness and brought us into the kingdom of the Son he loves,
in whom we hold redemption, the forgiveness of sins." Col 1:3-14
If we reject faith and stop remaining in Christ, then in whom do we hold redemption?
5th: God 'buying us' doesn't mean He bought us from Satan or some person and that person or Satan would have to 'buy us back.'
We were redeemed from the curse of the law,
Galatians 3:13; from God's wrath,
Ephesians 2:3; from guilt and bondage to sin,
Romans 3:19-21; and redeemed as God’s property (
Ephesians 2:19;
Ephesians 1:14.) The price God paid was the blood of Christ (
Matthew 26:28;
2 Corinthians 5:18;
Ephesians 1:7;
1 Peter 1:18;
Revelation 5:9, etc.) The church is represented as the property of Christ and in some sense our redemption reflects our corporate redemption as God's people as well, much as He redeemed Israel. But who did God 'pay' the blood of Christ to? Not to Satan. Not to us. Not to any human. Rather, Christ shed his blood as our kinsman redeemer - the Jewish practice that a kinsman could pay the debt of another. The 'debt' was our guilt under the law and hence our bondage to sin.
We don't have to 'repay' that debt. God erased it. No one owes it to anyone anymore. The account is closed. But when we reject faith and return to the law? We no longer have basis to claim our sins 'covered' by Christ and will in fact be incurring new debts moment by moment. We no longer can claim the redemption of the King. We exit God's redeemed people. We return ourselves to being subject to the wrath of God. And such a person *does* pay their debt - at the judgement when they are cast into the Lake of Fire.
