Well when someone is breaking the law, gets an order from law enforcement, and say no then…yea they are generally forced to comply. Police are far from perfect, but that is why they are called law ENFORCEMENT.

A solution to the problem as a whole is much more complicated and nuanced. If you have children, are disabled, or actively want to be a contributing member of society - housing. If you are severely drug addicted or mentally ill to where you cant be treated + violent - forced institutionalization. If you just want to live with no accountability, don’t want a job, or just just want to use drugs all day with no desire for treatment - go live in the woods where you don’t bother people. There is a lot more nuance & funding constraints here, but that’s my oversimplified 2c.
