This is true. Talk about freeing transactions from interference from "corrupt governments" sounds wholesome when you portray it as an activity between marginalized people in regressive societies, but that's just fantasy. If such a thing existed- and I'm not sure crypto could even accomplish it- then crypto would become a tool for transferring wealth in secret around the world, which is the goal of the super-wealthy who want to maximize their ability to exploit people and pass on the costs of maintaining the commons to the exploited.Doesn't really matter, because Bitcoin is where all the interest is at the moment, and where most of the investment money is being pumped. The fact that you have dozens of PoS cryptos on offer means nothing if nobody is interested in them.
Besides, PoS is literally a 'Rich-Get-Richer' system, so if it ever did take off as a currency, it would just create yet more inequality.
So aside from creating hardware shortages and burning massive amounts of electricity on a planet that's fast approaching a climate catastrophe, crypto -in whatever form it takes- also completely fails to change the status quo of wealth inequality.
They're already doing that without crypto but hey, maybe it would make kleptocracy a little bit safer for the kleptocrats.
