But my theory is someone, a "Bitcoin OG", will campaign for a hard fork to increase inflation without increasing the monetary supply, if the price remains low and the block rewards halve to 3.125 on 2024.
It starts there, and it will not be the end of it.
While I'm skeptical about your "theory", and your "bitcoin OG" (Is the real satoshi going to rise from his cybergrave? lol), I can't say I'm not excited about the future.
The "OG" might be a developer, a miner, or a whale-cumulator like Barry Silbert.
By 2024 on the halving to 3.125 rewards per block, and on the condition that Bitcoin's price has not increased high enough to support the miners' operating costs, someone will campaign for a fork to increase inflation, but without increasing the monetary supply to "save Bitcoin".
It will be another big drama same as the scalability debate.
I hope you understood my point this time.
