As a currently homeless person I still support NASA existing and working on cool shit like this.

Far more reasonable ways to fund helping the homeless would be uh, tax the rich, or make housing a right, universal basic income, or in my case in particular, sending me some money.

And no that is not a joke. Study after study have shown that by far the most cost efficient way any individual or organization can be in helping the homeless or those at risk of becoming homeless is just give them money without making them go through a nightmarish slog of confusing bureaucracies.
