Vitalik's refutation to Song's argument against proof of stake was accusing Song of Ad Hominem where there was none, then a direct appeal to authority. No actual counter given...

Proof of stake "validators" are anticompetitive actors acting in a socialist system where the system operates on authority based on trust of stakeholders rather than egalitarian competition based on effort. The difference between bitcoin and POS is the quite literally the difference between socialism and capitalism.

The whole point of bitcoin is its trustlessness. Shitcoiners are going to shitcoin.
