Do I really need to say why banks are terrible? What your begging for is fractional reserve banking through bitcoin to appear. Banks are EVIL. They do not create wealth in society they steal it by creating debt without paying for it. Their only needed service is to be a middle man to secure "funds" and provide better liquidity (real gold is not liquid), which right up until bitcoin is the only reason why they needed to exist.
The cheap credit that banks create through fractional reserves are DIRECTLY responsible for the misallocation of capital that causes unnecessary hard ship.
You're refuting your own argument again. The fractional reserve system is not evil, but the monopoly that governments/central banks on our money systems (traditionally) has caused the system to create it's own busts and recessions. But fractional banking per se is not the problem, rather the lack of competition is the problem. Bitcoin as a settlement system would attend to this problem and it also attends to the inefficiencies of the existing solutions.
Real gold is not liquid in a certain sense that it is costly to transport in relation to other solutions which exist to allow settlement without always moving assets such as gold (this is another reason why bitcoin doesn't actually need increased tps in order to stay relevant and valuable.
We can turn to Smith to understand how the system could be used to keep bank loans and money printers in check:
Hayek also explains this in the denationalization of money which is simply an argument about what would unfold if the monopoly on money printing was ever broken. This exactly what bitcoin did, and there is no part of the argument that requires the new money to have a higher tps than bitcoin.
John Nash also gives an extensive argument to how such a system would benefit the people by being used not so much by the citizenry but by the meta players.
I've cited and summarized these arguments, and they ARE founded: https://thewealthofchips.wordpress.com/2015/07/12/a-general-summary-for-john-nashs-proposal-ideal-money/
