Yet, somehow, welfare, food stamps, medicaid, social security, etc etc etc still keep writing checks when the economy is down. Ok, so wipe all those out (including the significant overhead of running each one by its own, separate organization), and send the checks to everyone who's a citizen.

This is already happening. See above. It doesn't run out if you have a functioning economy. I'd also argue that GBI would make the economy function a lot better by opening up business opportunities to those who don't have access currently.
