Why don't the fed just print money, a program could order stuff on amazon and they could deliver it to a land fill (obviously the landfill would have to be automated by robots).
for services they could just automate making bookings with a deposit and not show up. or a little zoomba vacuum thing could show up.
wouldn't be inflationary as cash is being destroyed like mad as we are all replaced by robots, so that won't be a problem.
