I don't know where you're supposed to live, but you don't have a right to live on other people's land or to camp on most common land. There are definitely places where you can go and no one will care. That is where most of the people who are today homeless should go. All able bodied people should. A lot of people claim to be disabled. it's hard to know what they could do if they tried, if you don't make them try. I think just about everyone can be more than a burden to the people around them if they choose it.
