I think people are missing the mental illness part of this. My father, a disable vet, pays no taxes of any kind, and no medical bills. He lives in Oklahoma where disabled vets pay no sales tax (they get a tax free card) or property tax. The VA pays 100% of his medical bills, no copays or deductibles. He get 50K/year in various benefits (disability, SS and pension), and has about $500K in assets. His remaining life expectancy is about 12 years.
He lives in a run down trailer in the middle of nowhere with no neighbors (he was able to get the land for 10K, the cheapest he could find). He has no working AC (the part to fix it would cost $50 and he thinks that is too expensive), no running water in the trailer (the pipes froze and the plumber charges too much), buys expired food at the scratch and dent, and cannot hear because he will not spend money on decent hearing aids (the VA ones are free, why would he spend his money?).
If you met him, you would think he was a very personable and normal person. He is not mentally incompetent except for his living situation. There is no way I could get his declared incompetent, we have discussed this with a local attorney.
He is clearly mentally ill, but you cannot force treatment anymore. What to do? I do not know. Unfortunately, I am waiting for the phone call that he was found dead in his trailer.
