This is exactly the thing about Bitcoin that concerns me most; it has economic implications baked into its design and operation, but We, the People, have no voice in deciding those implications.
What if We, the People, want to change the inflationary/deflationary properties of the money? If we're on bitcoin, someone else made that choice for you, and you have no recourse.
I'm not at all comfortable giving away that kind of agency; after such a long arc toward greater democracy, it's hard to see bitcoin as anything but a substantial step away from democratic governance.
