“Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.”
But if your question is if I believe in absolute freedoms, I absolutely do not. You are not free to harass people on the street. Not free to monopolize public parks. Certainly not free to be violent.
I wonder who it is you imagine will administer this involuntary servitude program? Does it particularly matter if the work is done to some standard or other? Do you imagine the state of California is competent to manage this system?
I'm not sure how giving someone a home and money for essentials is involuntary servitude. If these people don't want to do the service they can get a different job. I just realize that a lot of the homeless have what it takes to be successful, they just need structure and a little help.
It's tricky.
