Firstly, that's just naked projection. Secondly... GOOD.

Sincerely, we need to treat people who can't or won't conceptualize 'enough' as hoarders with mental illness. He can never use his immense opulence or spend all of what he has, and he can't be happy with it either. He should be separated from it, given a stipend that will meet all his needs and desires from it while he GOES TO REHAB, and the rest should be reinjected into the economy for social gain, and used to pay for the public programs and systems that made society work to begin with. Mostly because if it never worked he would never have had this opportunity to destroy it for his own pride.
