It's arguable that fiat power for each state similarly reflects preferences of banks, merchants and users. However, some of us doubt that money policy typically favors users.
With government fiat, forking isn't really possible, without a revolution, no matter how unhappy users are. But with Bitcoin etc, that is possible.
It's a common misconception that miners drive Bitcoin policy. In my opinion, miners are parasitic. When I first started using Bitcoin, there were virtually no professional miners. Users did all of the mining, locally. So difficulty was very low. Now, with so many professional miners, difficulty is very high. However, blocks get solved in 10 minutes on average, just as they did in the beginning.
Anyway, it's true that Bitcoin is a fiat currency. But governments aren't in control, and that's a good thing.
