PoW is just as much depending on fiat currencies. You can't get electricity without paying for it, you can't get a mining rig without paying for it, etc. This is one of the more common critiques against PoS and it just doesn't hold true at all. With the decentralized finance ecosystem, you can put any supported asset to work and earn ETH or stablecoins or anything else you want and accumulate that way.
Maybe I'm an edge-case (I don't think so), but I was able to use the hardware I already owned, and the electricity already included in my utilities bill to acquire enough Ether that would allow me to deploy a smart contract. That won't be possible anymore in the future. So you're factually wrong, at least in my case.
It's ridiculous you talk about financial privilege. Who the hell do you think owns most crypto? You think it is people living on the streets in India? Children in Africa?
You sound super delusional. I can't believe it.
Mining at a rate necessary to get any reasonable amount of Ether is a huge investment, and is already out of reach for the average person. Setting your desktop computer to mine definitely won't pay for your small smart contract.
I started mining on my own PC a couple weeks ago, with the GPUs I already had (2x 1080ti) and made about 0.5 Ether so far. So it's definitely not impossible to get enough currency that enables you to interact or even deploy a smart contract on a consumer PC with a little bit of time.
I actually had to spin up a Virtual Machine with GPU passthrough to launch Windows because I couldn't get the GPU tweaks working on Linux. Really nice how vfio is now in the Linux kernel, it's been a breeze going through the setup (compared to a couple years ago when you needed a custom kernel.)
Thankfully with ETH 2.0 the cost of publishing data on the chain will drop dramatically (there will be ~63x increase in throughput of publishing data, not transactions) so contract creation should be cheaper.
But really if you are interested in the space it might make sense to just publish on an L2 like polygon.
There's no inherent weird dependency on cash, there's only a dependency on whatever currency people choose to pay each other for work, which currently happens to be cash.
If people started paying each other in Ethereum-based tokens, you could close the loop and cash would not be a dependency.

Do you want to be a citizen of that new government? What will they do for their citizens? Do they plan to build roads or anything else?
Seigniorage should go to the people not the capital holders.
Also, if people don't think there will be validators for each wallet with 32 coins -- which are producing Co2 -- then they are wrong. It just changes the game, not the incentives.
And the validators, PoS anyway, use very little energy even compared to traditional coin minting.
On a side note, I have mixed feelings about PoS. The idea behind Ethereum - that is, as I understand it, being able to deploy smart contracts using a Turing complete language -, is pretty intriguing; but the costs associated with doing so put me off. I tried to estimate how much it'd cost to deploy a fairly small smart contract a couple days ago (admittedly when 'gas costs' were high), and it would've been several hundred dollars, perhaps even surpassing a thousand. It seems like PoS would lower that, which is good, but comes at the great cost that people who aren't already in the game won't be able to acquire Ether without basically paying cash for it. That's a weird dependence on fiat currencies for a 'decentralized ledger'. (And yeah, there might be other means, but none of them are really practical for the average person.)
If there hadn't already been cryptocurrencies, nobody would've thought PoS to be a good idea. A bunch of people who hold some digital certificates that predictably multiply themselves want people to give them money to 'acquire' those? That would've sounded like a scam to me...
