You didn't answer what was wrong with any of that, (wandering around a market in a football kit, doing odd jobs, listening to a radio, whilst having a mental illness) you just added one (swearing) .
It seems like you know your point is weak.
So, what's wrong with any of that? Or are you just being mean spirited and intolerant of someone who became ill, just like any one of us can?
Someone would need to be a risk to others or themselves for the powers that be not to allow them to wander.
Times change, yes. Not sure I like your vision of the future in which the council lock up anyone who doesn't fit your idea of normal.
