> What principle allows us to restrict smoking on private property that wouldn't also allow us to restrict people feeding the homeless?
Principle of "you have your freedom as long as you do not restrict other's freedom". Smokers restrict freedom of those who want to breath air that is not harmful. Hobos restrict freedom of those who want healthy sanitary environment without drug addicts and asocial behavior in public space.
If you want to allow hobos to live as they live, you also have to allow anyone pull their pants and piss right near you in bus or park, allow anyone to harass anyone else for no reason, also allow your kids to communicate with asocial people that have nothing to lose whatever they would do. If you actually think hobos do nothing bad to people you have not met any hobos.
