With PoW all that burned energy creates a strong root of trust.

How do you establish that root of trust with PoS? Currently approaches are ultimately circular, IE trust it because the majority holders of the coin are continually voting to trust it.

You need a good initial distribution.

With Bitcoin mining pools it looks like there's just as much centralization (if not more) as with proof of stake.

The difference being you don’t need to ask existing Bitcoin miners for permission to begin mining Bitcoin yourself. Conversely, staking is inherently impossible without first obtaining “stake” — and how can you obtain stake without the approval of existing stakers?

[Tepix]

You don't need permission, but you do need money to buy mining hardware. Might as well buy a stake for that money instead. Same thing, isn't it?

> Same thing, isn't it?

US dollar payments aren’t subject to the approval of stakers, and existing PoW miners have no on-chain mechanism to prevent new market entrants from competing against them for hashrate.

So, “no”.

To begin staking, you first need stake. But merely transfering a PoS coin from an exchange to your own wallet for subsequent staking is inherently impossible without the approval of existing stakers. Even this isn’t enough: existing stakers must also approve of your initial staking transactions.

Which is not how PoW mining works.
