One only needs to look at modern democratic politics to have _serious serious_ doubts about that argument...

It won't surprise me at all if a PoS blockchain ends up looking just like a two party political system, where every now and then you get to choose which fork/party has the least objectionable outcome for you, but where both choices leave you worse off than you started...

Except that in this case, if you think you have better ideas, you can code up your own fork, and try to drum up support for it. The open source ecosystem works far better than the political system, I find.

Like now, you can drum up support for your own new party.

Yes, but in the case of the US government at least, there are structural reasons why the two party system is a stable equilibrium. Those structural reasons do not exist for cryptocurrencies. The most important of which is that there can be only one president of the US government, only so many senators, judges, etc... There can be infinitely many concurrently competing forks of Ethereum.

You and I can go fork Ethereum right now and now just tell people it's great, but show them it's great. It's like if we could fork the US government, refactor all the policies and let it run to demonstrate how good it is, and then people can come on board. You can't do that in politics, but you can absolutely do it in crypto.

Half the point of a cryptocurrency is the network effect - so I don't see how your argument holds, at all.

It is not clear at all that a small political experiment will scale to a super power. It is equally unclear that a small crypto currency experiment will scale.

This is without even touching on how easy, or difficult to it is rally support for a new system. Quite difficult, I'd say.

> Half the point of a cryptocurrency is the network effect - so I don't see how your argument holds, at all.

It holds because you can demonstrate its utility on a small network.

Network effects are too powerful. If they’re smart, they’ll make small changes over a long time, only ever upsetting a minority at once, and so the users stay. That’s Facebook to me, other things to other people.
