Did you see my point though, that some things that are considered to be sin are actually material things of this world that people happen to like?
YES! That's the problem with sin, we LIKE it. You seem to have great insight into how the devil uses this sort of thing, how to recognize what's going on as it happens, and what to do about it. My efforts are largely to shine some light on that, and bring it out into the open for all to see, because we can't help but benefit.
Scripture speaks of "the pleasures of sin for a season," which is only one great reason to read Hebrews 11. So the devil tends to "show" us this aspect, (a good working definition of carnality?) and hide the negative consequences which are (at least primarily) Spiritual. There is also a parallel here to who Lucifer was before his fall, and I think this gets right to the "root" of the tree under discussion

But that is even deeper than what I have unsuccessfully tried to convey so far, so I'll leave that alone for now.
Backtracking to our previous lack of communication, you said "God wasn't speaking to you through that." Try this angle:
"Through wisdom is an house builded; and by understanding it is established: Proverbs 24:4 And by knowledge shall the chambers be filled with all precious and pleasant riches."
Those 3 words get a LOT of attention in Proverbs, at least in the KJV which uses them consistently throughout all books with the same meaning. Also significant is that the word in the original Hebrew is the same, as well as re: the tree of the knowledge of good and evil.

So it's important (especially for unbelievers) to realize G-d is NOT anti-knowledge! So often I see that accusation made, and it just distorts everything.

What then is the usage of this word, "knowledge?" When I was a new follower of Jesus, something He showed me may be helpful here. Looking back at the above passage from Proverbs, He showed me
wisdom is seeing the difference, (between good and evil, right and wrong, holy and unholy, etc)
understanding is choosing the better of the two, and
KNOWLEDGE is what we get as a result of those choices and our pursuant actions.
These fit perfectly with everything the book of Proverbs says, and the idea has never led me astray. This adds insight to A & E's events at the tree ...
