I think you're misconstruing the original suggestion, which was that a legal solution to the problem of the unbanked would be viable. You could pass legislation mandating that banks turn no one away, you could establish a publicly run bank of last resort, etc.
I believe those measures would be "easier" solutions to the problem than replacing the entire financial system, but that's just an opinion about a hypothetical.
This is the one I'm specifically discussing, its from a different user. This is the line that started the thread. Plenty of users are discussing this specific line I believe.
> The same as national health insurance. You make a law that everyone must be served by the banks. Easy.
and national health insurance is famously a fiendishly hard public policy issue (albeit one for which several competing models exist and have been put into practice). Working from an existing public policy model (like using France's example of offering bank-of-last-resort services through the postal service) still seems way easier than just deciding to solve it with crypto.
Yeah, I don't disagree that crypto won't fix this. I just disagreed that it was "easy". I took them as being literal.
