That's a hilarious but wild comparison. There are specifics about feudalism that don't apply to crypto even metaphorically.
The less hyperbolic analogy would be shareholder corporate governance... the more shares you have, the more skin-in-the-game, the more the decisions affect you so naturally your voice weights more.
In your model, cryptos are progressing towards democracy, but I would disagree; democracy is not the culmination of the governance evolution. I'm more with Plato here who considered democracy a degeneration.
Democracy is what got us into this mess in the first place (brrrrrrrrrrr); the most oppressed minority in the world is the individual, and it's oppressed by the whims of those who represent the majority.
No, in my model cryptos are not progressing towards democracy, but are progressing towards the neo-feudalism.
We can observe the tendency that the rich are becoming richer and the poor remain poor. The nowadays crisis might slow down these tendencies (like big wars in the past caused shift in power and less economic inequalities), but I think they will remain. I agree with you, Plato and Aristotle on democracy, that's why I don't want to repeat stupid phrases that "we need to increase taxes", "we need to help the unbanked", etc. etc.
Some day I plan to evolve more in writing on this subject. In a way, this progress might be cruel especially for some categories (the latest Black swan already harmed many people, and along with future conflicts and technological advances such as robotization and AI more people will lose jobs, etc.) but what's positive is that the rise of crypto might bring more interesting people to power and to important positions ("social lift")
