As a counter point one could imagine a hypothetical implementation of MMT where money was printed in a particular room at particular times of day, and those in the room were able to capture the money. This would of course help the government offload distribution of printed currency and avoid direct corruption. Given the room can only hold so many people those in the room will have had to wheel, deal, and bribe to get make their way in.
As its impossible to have a taxation room as everyone would simply avoid the money pit, the government would of course need to still tax all market participants according to some taxation scheme, presumably the government would tax investments less than income to keep the money velocity from falling.
We'd be left with a hypothetical economy where ~100 individuals/corporations get dollars printed at them and a taxation system which taxes what those individuals happen to spend in the rest of the economy. Creating a natural monopoly for those with a spot in the room.
