I'm not sure how citizens using crypto to buy bread and milk helps prop up bad governments? To be clear, in the kinds of governments I'm talking about here the people at the top are entirely and completely insulated from the day-to-day struggles of their population.

Most will have offshore accounts hidden in various shady or neutral jurisdictions that will ensure they live out the rest of their days without issue (see Zimbabwe, Nazi Germany, or recently Sri Lanka). They could even wipe out large swathes of their population completely and it would still do nothing to destabilise the government (again, see Soviet Union, Nazi Germany, Khmer Rouge, the list goes on)
