> there's efficiency to be had and red tape to cut
Depends. In the USA, yes, your banking system is utterly shite, despite the supposedly numerous volume of different banks who are supposedly able to innovate and compete.
But.
that red tape is there to prevent a bank from collapsing. Its been imposed as a reaction to numerous financial crises.
There loads of rules that govern how much money a bank can loan, and how much they have to have on hand and in what classes they need to store deposits in.
A bank can be wildly profitable if it doesn't care too much who it lends to. Riskier debts yield much greater interest. The problem is, as soon as confidence takes a knock, the entire bank collapses because the value they claim they have is not backed by any kind of liquid asset.
This is the same with crypto. A stable coin is wildly profitable when people are pouring cash into it. but all it takes is a small wobble, people rushing to convert the "coin" into another asset class, and the whole thing crashes. This might be because they really don't have enough reserves to cover the withdrawl, or it was fraud. They aren't regulated, so we'll probably not know.
