Then what are you suggesting?
If you accept that people shouldn't be 'forced' to accept the help that is available which may include adjusting their behaviour to do so then that's fine.
But you also shouldn't think that wider society should be 'forced' to accept the antisocial behaviour implicit in people who do choose that lifestyle.
Despite the assertions of many on MN, there are people who choose not to be housed or are intentionally homeless through their behaviour. Same as some alcoholics choose to continue drinking and some addicts continue to choose to be addicts, and some sex workers choose to be sex workers, and some drug dealers choose to be drug dealerw despite help being available.
And some people are of course in need and would want help but that's not on the whole, what this proposed policy is about.
A lot of MNetters choose (when it suits them) to believe a lot of people are victims with no personal agency or personality or character of their own who could do just better with the right help, when it's not always the case.
