> But then you've lost all of the advantages that the blockchain was claimed to possess.

That's a very wide brush stroke to paint. You just have to analyze each use case independently.

In the same example of land registry, just a transparent history is a huge value add when dealing with corrupt government officials. Here's a case study https://s3.amazonaws.com/ipri2016/casestudy_collindres.pdf . Voting transparency even with the government as the part of centralization is a huge value add imo.

Further, even allowing centralization in certain points, like a SpaceX IPO (which should def be centralized), allows whoever holds a share to make arbitrary, trustless mediums and rules of exchange.

How does the blockchain ensure that I can both verify that my vote was counted but can't sell my vote? https://youtu.be/BYRTvoZ3Rho describes one electronic voting system that's supposed to have those important properties, even though I don't fully all the details yet.

Depends on the specific implementation. Just because you do it on a blockchain doesn't mean you can't require people to show up to a polling center and sign transactions in person.

With Ethereum, one way to do it is to make the voting weight non-transferable, meaning to give someone else your vote you'd need to give your private key.

It would be of course crazy to do that; like giving someone your bank card and PIN number to give them cash.
