true trust often only emerges in small, tightly knit groups of people
it is so small to make the utility of ecash or similar trust based systems useless for 95% of use cases
Discussion
Maybe that's enough, and the other 95% use another solution.
But for that 5%, it's better than all the alternatives, so it has to exist.
That 5% is what we might call “shared accounts/custodians in a single small community”
And it’s certainly not ecash
the game theory of trusted third parties should have been obviously a bad element of the architecture for anyone pretending to be part of bitcoin lol
in security design you already assume everything is untrusted until proven otherwise, most trusted components are limited and internal, and whatever external “trust” exists is limited to the bare minimum
