Just because you can join a staking pool which often takes a cut and makes it easy doesn't invalidate what is actually going on.
> The barrier for entry in the legacy financial system is way way higher. Have you ever applied for a banking license?
One doesn't have to have a banking license to use the local fiat currency of one's nation (basically, one is born into it). And one must do almost nothing to get a check from the government if they decide to stimulate the economy by handing out money to those who showed they had very little on their last tax return.
If you're into UBI type stuff, yeah, there are multiple UBI projects on Ethereum https://www.proofofhumanity.id
There are a ton of other projects that allow people to share storage space, compute, art, information, etc to earn cryptocurrencies. People contribute what they can to the network, and are compensated for their efforts. Projects like gitcoin are raising millions of dollars for people who volunteer to provide public goods, from performing security audits on large open source projects, to cleaning plastic out of rivers (https://gitcoin.co/grants/). Seems to me like the Ethereum ecosystem is far more altruistic than many current governments.
Can you buy the same things for 1 USD as you could then? (no)
1. If you want to run a validator node, i.e. run the architecture you need to have 32 ETH to be eligible to provide this service. And it does not mean immediately that you will earn something. https://ethereum.org/en/staking/
2. If I stake the equivalent of 5 USD I will likely get a 5% return on it per year making it much less interesting from an investment perspective given volatility and opportunity cost.
3. Staked funds are locked and can't be used anywhere else or for anything else. At least GPUs can be used for mining AND general purpose computing.
4. It is much easier to go to any random money exchanger and go USD/EUR or USD/JPY
5. Getting a retail bank account can be done in a matter of minutes online.
Both Ethereum's and Bitcoin's regular nodes don't make any money.
