This is a spurious comparison, traditional banks provide orders of magnitude more services to orders of magnitude more people.

One day, could, will.
But still isn't and doesn't. With a background of a world scrambling for cleaner power to mitigate climate change. That's the problem.
I still prefer Ethereum's variation of Proof of Stake over Proof of Work, but it's by no means clear to me that Proof of Work based blockchains are less resource-efficient than traditional financial systems, and I would wager a comprehensive analysis would show in fact that they have the potential to be vastly more efficient, if they're allowed to scale up their transaction throughput to amortize their energy consumption across more numerous transactions.
This is just more nonsense.
A bunch of automated nodes, strewn across the globe, and connected via the internet, maintain the network, with the network being able to seamlessly/autonomously manage nodes joining/leaving.
There are no legal contracts that need to be drawn up, filled out and signed for someone to start submitting PoW, or validating and propagating transactions, to the network. There is no HR department. No payroll. Just machines, and a deterministic compensation mechanism, managed by a fault tolerant network of machines.
