I forgot to mention the biggest bans here in NYC:
smoking bans in restaurants, bars, and public work spaces
Smoking bans are now common place almost every where - this is one of those bans I support. In this case, because smoking impacts the people around them. It is almost like by smoking in these places you are banning fresh air so it is like a ban to prevent a ban (although my thinking is always a bit weird).
But in reality - the only bans I can see supporting are those due to then direct impact of people around them. For example, banning smoking in people's individuals houses wouldn't be right as it only impacts the people who live there. Whereas banning smoking in public work places, directly impacts the other workers.
And the ban on large soda is plain old stupid. Although I rarely drink soda - if some one is dumb enough to drink down a whole 5 liters of soda in one sitting then the deserve to be obese.
