Some portion of the answers to the objection that cryptocurrency increases the level of unaccountable power seem to be being met with "but look how unaccountable power is now", which misses the power. Boy, yes, power is pretty unaccountable and those with their hands on the levers of power seem to be the wealthy.

Those who benefit from cryptocurrency are also the wealthy, who can use this along with the other levers of power to increase their influence and increase their wealth. There's counter balance to the power of Fed here.

I'm not going to say it will be successful in that aim, but the idea that governments can simply create currency by fiat, donate it to their powerful, insolvent friends, pass the cost along to your grandchildren and/or degrade the value of your savings is not what I consider to be a democratic system.

Was it actually, though?

And ironically it works the same way in crypto. I bet the traditional financial markets wish they could "roll back" financial calamities like the Ethereum DAO hack - the founder of ethereum lost money so oops, hit the undo button, roll back every transaction on the whole network. That's the exact same sort of "socialism for the elites, capitalism for the rest" as crypto boosters complain about with USD.
