The ideology of people not needing a central government's permission to privately interact?

What I would concede is that it does challenge the dominant ideology of the establishment.

As this former Federal Reserve economist describes, the Federal Reserve system is extremely centralized:

This is just one aspect of centralized economic control cryptocurrency threatens to upend.

Centralization will inevitably engender rent-seeking, so the dominant ideological framework being one that glorifies that centralized gatekeeping, and villifies a free market, is entirely predictable.

Common arguments in opposition include: the existence of less energy-intensive cryptocurrencies (proof-of-stake), that cryptocurrencies provide safer ways to donate and engage in finance for people in oppressive countries

I don't see how energy efficient currencies and allowing safer ways for people in oppressive countries to donate is ideological

Accepting the war-driven petro-dollar is equally ideological.

since when?
