To add, what you're touching on in your response is the "Impossible Trinity" of monetary policy[0][1], which states that any two of the following three options are compatible, but it's impossible to have all three at the same time: a fixed exchange rate, free capital movement, and an independent monetary policy. It seems as though at the start Bitcoin picked one (free capital movement) and only recently has realized that it left something on the table. And a very important something, at that.
