But if that mutation needs majority (from miners or stake holders) how is it any worse than a democratic country deciding to change a law or print money or whatever?

Wasn't the main part of the allure to blockchain/crypto to be better than democratic societies and institutions? After all that's what they are trying to replace right? Governments can't be trusted and all that?

Presumably it's a lot harder for a group of evil-doers to get a country into changing laws or printing more money. Your opinions may vary. I have my faith in (some) countries.

It's far worse because it lacks any kind of controls or process to make sure everybody gets a fair shake. A good government answers to all citizens. Blockchains answer to those with the most hash power (i.e. $$$$).

You are effectively saying you'd prefer mob rule over due process.
