I would argue without evidence so please dont quote me that this number is subsidized. If the government sees the money supply shrinking it will intervene and put money in everyone's pockets because in order to actually fix the economy the government will have to shrink which it will never do voluntarily.

So the money supply will always grow as long as there is government and there will always be government. We are just not intelligent enough to live without it. And thats not because the government is good, its because its bad. As a species we lack the ability to understand and accept that :)
