That really is the purpose of this particular NAP. If you don't like it, repeal it and chalk it up to lesson learned and don't vote for it again. It will never be an issue if you don't vote for it.
I was a little surprised to see my stuff taken, but then I thought "of course!" How fair is it that my sim can take from everyone but they can't take from me, or they can't take off community lots but I can? I guess I'm not used to thinking in a way where my actions have consequences in TS4, but I'm kind of liking that they do now and it's making me think a little more beyond what my own wants are.
