You're thinking wrong. The ultimate goal is to not have any direct connection with fiat, but to have 1 satoshi be a unit of value on its own. That's my prediction.
By the time Bitcoin reaches $1 million (as per your prediction), fiat has likely taken a massive dive, which will directly mean that Bitcoin's $1 million valuation might be worth just $50,000-$100,000 in today's purchasing power value. Fiat in terms of purchasing power is stricly one way traffic down to the south, and governments can (and likely will) speed up the process of value loss by messing up.
We have to step over that. Bitcoin is our one time opportunity to actually force through a significant change in the way we see and use money.
That's some mindblowing shit you got there. I never thought of fiat getting devalued while bitcoin inflates. If a satoshi ever becomes a unit of value, that's the exact time where we adopt bitcoin as a currency.
Right there, what satoshi wanted to accomplish years ago gets accomplished. Bitcoin can change a lot of things around, but its the people that have to do something about it. People are focusing on unnecessary things and are getting rich for it(look at the stupid ass youtubers).
