You want to leave drugs users, on the most potent substances ever created, in open-air drug camps full of violence, rape, filth, more drugs, etc? Do you expect them to one day pull the fentanyl out of their arm and walk over to the Apple store to get a job?
The drugs, and the camps, kill people. If they don't have the wherewithal to move then we need to do it for them. They can't get better while living in filth and honestly can't choose to do better. Once they're imprisoned, in a drug program - not a jail, for the 3-5 years it takes to actually detox they'll be ready to start to get clean and on their feet.
