when you purchase property, you can control who is allowed on it
If my car is run off the road onto your property, you can order me off your property, but I dont think you can keep my car by not allowing me or my agents on your property to recover it.
Straw man.
No. Its a postulation. A postulation is a suggestion or assumption of the existence, fact, or truth of something as a basis for reasoning, discussion, or belief.
A straw man is an intentionally misrepresented proposition that is set up because it is easier to defeat than an opponent’s real argument. Sort of like your calling my postulation a straw man.
As for the rest of your post, we are pretty much in agreement.
