hmm these seem to be usecases that are almost impossible for bitcoin/blockchains that say "cheap transaction fees / trust in the system" due to no-person-in-the-loop...
Yes, it's "not a problem" because all transactions are final and if you lose the key to your virtual wallet with all your savings, then you're fucked, but that's part of the point?
Banks provide these essential services that people need. Bitcoin doesn't, and it still consumes massively more energy.
I just noticed you were listing vital features of a financial system, and yet wasn't using them as your foremost argument.
The idea that 11 people bidding up 10 houses is going to radically change if you have Bitcoin or a narrow bank is ridiculous. If people borrow Bitcoin for the loan, they will still have to outbid everyone else at exactly the same price measured in dollars, because eleven people are bidding up 10 houses.
I am honestly quite tired of nonsense like your comment. If the economy is in general equilibrium, then there is no meaningful difference between Bitcoin and the dollar. If there is no general equilibrium, I would expect Bitcoin to be further away from it than dollars.
60 million real people. People that forget a password, lose their wallet, encounter fraud, need to walk into banks occasionally, use debit cards/deal with cash/ATMs, credit cards that are also accepted everywhere, and as you point out financing products people can actually use (not some crazy smart contract DEX who knows what), need help, have questions, etc, etc, etc.
Safety deposit boxes to notary services the list just never ends. This is just retail.
Plus little things like at least trying to comply with the law, customer protections, regulation, oversight, fraud departments, etc.
People that even bring up comparison to the banking or financial system in discussion of bitcoin power usage instantly have zero credibility.
Although the same could be said for almost any comparison between bitcoin and the banking system. It has total users measured in the 7-8 figures tops after 16 years for many valid reason.
