A similar issue will come up if we look at PoW vs. PoS. We can take Polkadot, for example, where dPoS (delegated PoS) is used. Polkadots inflation is 10% per year and these inflation coins will go to stakers, which are already rich and will make them even richer. In dPoS such rich stakers will be able to consolidate their power, which will lead to a massive centralization over time. Rich stakers will be able to abuse it. I'm sure we'll get a big discussion around it some time later, maybe in 2 - 5 years. 
side note:
i would not say rich. i would say coin heavy
elitism begets more coin holding but in pos inflation systems those coins lose value (buys less breadloaves per year)
back to the topic:
some say that chaos is ordered. no its not
chaos is random.
chaos is where so many random things are happening that evolution only grows out of the randomness of events colliding to create more energy than predecessor thus survives longer.
out of all the random things of PoW, timestamp servers, contracts. no one could see bitcoin coming until boom, satoshi let it all unite into a interwoven system thats unique and never seen before it
chaos is not planned or foreseen or mutually agreed
it has to take a step away from chaos to bring in a bit of unity to bring features and people together
again i dont think liberty is wild west, outlaw, no repercussions, chaos.
liberty does have some bare moral rules that all would seem acceptable etiquette. where its self governed and judged by peers. rather then hierarchical governed and judged by representatives
