Wouldn't America be better off if we were more careful about the laws we enact?

From both sides of the aisle. If the act doesn't hurt anybody else why make a law against it? Im a conservative and that would include gay marriage. And if I don't want to wear a helmet when I ride that should be up to me etc. There are way to many laws that interfere with personal choice. And neither liberal nor conservative is free from guilt on this. What do you think?
