I'd LIKE to live there too. But that place doesn't exist. And even I have been known to do stupd things from time to time (ok, all the time) that would probably get myself banned from said utopia.
Frankly, if the law didn't exist, I probably wouldn't know NOT to NOT do that.
So, perhaps a 'law' doesn't necessarily have to be in place for everything, but some general knowledge of stuff needs to be known before hand. gas is probably an easy one, but i assur eyou if you asked 10 people on the street why storing gas in a 5 gallon bucket is a bad idea, 9 of them wouldn't be able to tell you why, perhaps beyond 'because it might start a fire' or something else rudamentary.
Perhaps, then, it's our education system that has failed us. We are a country of fucking morons. If you don't believe me, look at last nights election results where 4 time incumbants who haven't done shit still happened to muster up 85% of the vote in their districts.....
