If people choose not to take on a mortgage or a rental agreement, that is their business. No where in the Constitution does is state that all residents of the USA must enter into any sort of housing contract.
That said, squatting on private property is illegal and owners are protected by a plethora of laws.
If you are wanting to give to others and decide that you don't need a house to survive, then you should be able to do that. I don't see why you would want to live in a box, but be my guest.
Also, if you wanted to spend your money on, say college instead of a house, then you should be able to. Nowhere does it say that you absolutely need to have a house built by one of those big-shot companies.
I'm not saying that it's a good idea to be homeless. It's not, because it's not very safe.
To tell someone else what to do. In a country that claims to love freedom, there isn't a whole bunch of people who will just leave others alone and let them enjoy being them.
You have to keep up with the Joneses. Conform. You have to be a Christian. You have to go to college. You have marry someone and, have children.
If you want to be homeless, you should be able to. Why you would want to, is beyond me. But, It is America. You are supposed to be free to do whatever you want.
Being homeless does not improve the world
and it is just lazy to be that way.A person who
becomes homeless will have to rely on the gov
to help them get food and other important things
and therefor it will be the hard working people who
will have to take care of them.
