We didn't really notice the lack of personal freedoms in the US before we started our travels through Mexico. When we started to realize all of the small things here that wouldn't be allowed in the US, it got us thinking.
It seems to me that in many developed countries, a certain attitude starts to permeate through society that says "I don't like XYZ, we should make it illegal!" If enough people start thinking that way, and before you know it, so many things are illegal!
I think a couple side effect of this are, for one, the lines between legality and morality start to blur. And two, people begin to take less personal responsibility.
Anyway, I hope this was comprehensible. I started out writing this comment with a different intent and it ended up going in a way that I didn't expect. I don't even remember what I set out to say! Haha.
