The government can actually fund everything and just print more dollars to make up the difference.
That is simply not true. The government may print arbitrarily much money, but due to inflation that will not necessarily fund everything. Who would accept worthless money in exchange for services?
If "TPOASIWID" actually raised further questions, that would be very useful! But it does not raise further questions. When I see somebody say that phrase, I assume they have no interest in learning more about the system as they already have the only answer they ever need. Who would say "TPOASIWID" and then go on to do a cost-benefit analysis? It is not the first basic step toward a critique -- it's the last.
