> deeply centralized institutions, the overall system continues to work
Until they don't. You are comparing the worst of decentralized systems (rug-pulls) with the average-to-best-case of institutions that centralize power (western democracy governments) when we should be talking about the extreme cases: autocracies and dictatorships.
> hardly a replacement for the existing institutions.
Why do people can only think in binary terms? No one is calling for the "replacement" of the institutions. The idea is to build decentralized systems as a hedge against the centralized one.
You are repeatedly giving the "so you are saying..." line and it's starting to feel like you are purposefully misunderstanding the point.
> Plenty of people are unbanked
For their own choice or because they were excluded of the system? Wouldn't it be good to have an alternative that we could have as hedge against them?
> plenty of people left Reddit
Not enough to cause it to implode, and not enough to bring a critical mass to any alternative.
