I think there is a strong possibility that, at some point, bitcoin will fork and the winner in terms of market value will be worse in terms of decentralisation, permissionlessness, etc. And due to network effects, it will retain it's higher market value.
Markets can be manipulated. ETFs and TCs could join forces and dump coins so a particular fork comes out with the highest market value. Plebs could be convinced to fight for a fork that is against their own interests. And this means, in the short term at least, powerful market interests could detrimentally control bitcoin's development.
But that wouldn't necessarily mark bitcoin's death: those changes could be reversed, once the pain of those poor changes becomes tangible.
Essentially, "In the short-run, the bitcoin protocol is a voting machine. But in the long-run, bitcoin protocol is a weighing machine", maybe? It could be corrupted, but in theory it could always be fixed.
Has anyone else written about this or explored this possibility? When I've seen people discuss this kind of thing, they always seem to assume that bitcoin will never be corrupted and will obviously survive forever.
