Bottom line is, no government can print money to get out of a recession or downturn. The deeper reason for this is that money is really a facilitator of exchange between people, a middleman in a trade. If goods could trade with goods directly, without a middleman, we would not need money. If you print more money you simply affect the terms of trade between money and goods, nothing else. What used to cost $1nowcosts$10, that's all, nothing fundamental or real has changed. It is as if someone overnight added a zero to every dollar bill; that per se, changes nothing. Just as giving every student 10 extra points on a test changes nothing fundamentally.

Also why the maximum number of 21M in Bitcoin is important because it never changes, not because of it's actual value.
