It becomes the government's and everyone else's business because who's going to look after you if you get disabled and can't work? You'll then have to proceed to beg, steal or live on government benefits and then you become everyone else's problem. As long as we live in a society we are our brother's keeper whether we like it or not. The only escape is to move away from society so you have no interaction with it so then you can't complain about society interacting with you. Which in today's world is impossible as society will still at least affect your natural environment, unfortunately.
