Just to be clear...you think owning a person as property and beating them is morally acceptable. I don't wanna go on before we're clear on that.
Neither will we go on from here until you answer my question.
I am interpreting your phrase "morally acceptable" to mean "good" or at least that it's not bad. As I've already said, that was not part of the discussion. But since you're trying to drag these things in, I'll point out a few things:
1) In Mark 10:5 Jesus notes that some laws were written by Moses not because they are "good", but to deal with the nastiness of this world. Note that the definition we agreed on is proper conduct toward a purpose. So, marriage is supposed to be a lifelong commitment. But what if the husband abuses the wife? Yes, because of that nastiness divorce is allowed.
So, now, suppose someone owes you a debt or makes war on you. How do you deal with that person? What if the system under which you live says you make them a slave? Can a Christian use that system? The answer is yes, but there are rules about how to treat that slave. In fact, in the book of Philemon, Paul is telling Philemon he needs to treat Onesimus like a brother. Slavery is not an ideal to seek (just as a broken marriage is not an ideal to seek). It is the result of our sinful world, and the Bible is explaining proper conduct for that situation.
The system in the U.S. is slightly different, and I am supposed to deal with debt and war per the laws laid out by the U.S.
2) I also get the impression you are speaking of "beating" as if it is unjustified and some gleeful sadism by the owner. I've pointed out repeatedly that is an improper facetious translation and I'll not accept it.
I've already said that corporal punishment is acceptable discipline (post #124). Deuteronomy 25:1-3 stipulates that it should be proportional to the misbehavior. It further stipulates that if the one applying the punishment goes too far, they themselves should be punished.
If you're going to disagree with me (and I'm pretty sure you do, but your moral system is blocking you from saying it), then disagree with what I've written. You're not going to tell me how to interpret the Bible - you don't even believe it.
Your turn to answer.
