It's very simple. The price of Bitcoin converges towards the price of mining it. Making mining bitcoin easier will only lower its price in the long run. So increasing block size will only increase the amount of hashrate in the system and thus the profit per dollar invested will not change that much.

Given this information, is it worth rocking the boat while mining is still very profitable? No.

> The price of Bitcoin converges towards the price of mining it.

Isn't it the opposite. The cost of mining converges towards the current price of Bitcoin. Because when miners get Bitcoin as a reward they immediately sell it for profit.

Well, yes, you could see it that way.

That's a shortsighted approach, in my opinion. The same pattern is observed in inflation: long-term, money printing has zero benefits. Why central banks do it anyway? Because there's a first mover advantage. Also, history has already showed us that, when given the opportunity, miners are in favor of larger rewards.

No, money printing has a serious advantage. It incentivize investment while taxing people who hold their money unproductively.

Yes, it incentivizes investing in better store of value like bitcoin (or gold, or Apple stocks).

Apple is only protected from inflation insofar as it makes real investments. Bitcoin is not a very good and significant store of value.
