You can easily increase the quality of life for 99.9% of US citizens by properly dealing with the very few well-known repeat "notorious" offenders—putting them in prison or mental institutions. This is an easy win, and that's a rare thing in the policy world. You do it, then life is immediately better for every citizen.
If your answer is it's morally wrong because of individual rights, then believe me, being in a fully funded institution is far, far better for someone than living on the streets in their own filth, tortured by their inner mental demons, and in constant anguish over who knows what.
Their own families (when they can be found) want this for them as well. That's often why they are out on the streets—because they became too much for their parents/grandparents/brothers/sisters to deal with.
You're doing nobody any favors, nobody, by letting these people roam the streets in anguish, creating even more anguish.

"I finally convinced my mom to buy a @Tesla after working there for 5 years. She did not want FSD but I made her get it anyway. After a few months of ownership, she gained the courage to try it and this was the result!"
