> in preventing corrupt state apparatuses from expropriating and squandering the meager private wealth

This is one of the greatest use of cryptocurrency imo. If you go back even a few years ago, formerly stable countries like Cyprus were raiding bank accounts to make up for their shortfall. As costs rise, and there are less and less people of working age paying into the system, governments will become more coercive in order to fund healthcare and benefits for the largest voting block. Crypto is a storage of wealth and a way to protect yourself from government expropriation.
