How is something cartel-resistant that requires that entities must accumulate more and more capital (mining power) to still be able to participate?

[tboyd47]

Mining profitability is an equation with many variables. If the value of the reward climbs faster than mining technology advances, we might see mining open to regular people again.

Also, the traditional cartel action of limiting supply to inflate price would not work in Bitcoin due to auto-adjusting difficulty.

And yet, in some sense, cartels are exactly what we have, in the form of mining pools.

less than perfect decentralization is still more decentralization than a monopoly. in this case the competition is a monopoly (eg fiat)

[QAPereo]

Anything that isn’t a monopoly is, “more decentralized than a monopoly.”

At Proof-of-Stake the "Proof-of-Work" is the value lost by stacking up tokens and not having them being productive otherwise. This value could be around 4% per year, same as having them on a safe invest.

The good thing is that you have to "work less" (just 4%) but if you are a malicious actor you lose all your stake (100%). In conventional PoS you can only lose what you invest, that is why PoS is so expensive.
