Good luck in enforcing a law like this one (if it becomes reality). The law won't pass though.
I love the reasoning behind the idea. A nonsmoker is whining about smelling cig smoke in a neighbor's backyard. LOL!!! That nonsmoker should mind his/her own business. I can see a smoking guest being rude by smoking on a nonsmoker's property though.
But banning smoking outside of a smoker's own property? Hilarious!
