I have no idea what is going on with those pictures and no idea how it's relevant for a discussion about thievery being exploitive :P

I guess it's about using the map layout and items to block entrances?
If you don't like to do that, don't do it. It's not needed

And again, I agree with you.
It should not be balanced around having to "break the game", but right now, I don't think it is.
