Confiscating 100% of all billionaire wealth (~$8.4T) covers - ~1.1 years of federal spending (~$7.4T) - ~4.4 years of deficits (~$1.9T) - ~23% of debt (~$36T):

Perhaps , but what about poor states like West Virginia or Alabama. It's not universal if they don't receive benefits also.
Absent a federal wealth redistribution, yes NYC must do its best for it's residents. I'm not disagreeing with that. A federal wealth tax, however, would tax Alabama billionaires as much as it would tax NYC billionaires.
