> Are you claiming here that things like banks and stock markets don't exist?
No, I am claiming that I couldn't spin up a bank or a stock market on my laptop, that is compatible with all the other stock markets, by forking a git repo.
> that have no non-crypto counterparts, are you referring to?
The git repo fork button, that slots right into a whole ecosystem that has 10s of thousands of contributors to it.
Ease of use, and developer experience and existing markets and existing integrations with all of these businesses is a big deal. It doesn't matter if someone could hypothetically spend 1 billion dollars recreating all of that, using a database. Because that would require 1 billion dollars.
