to change the consensus in a successfully way (ie: without risking that your fork goes to 0) you don't need the majority of users, you need the majority of the economic power. Let's say that within that date the govs manage to get 80% of the supply (via ETF or by law-enforced custody of user funds or simply because users keep their stack on exchanges). In that case they can successfully change the supply

So you’re referring to a 51% attack, correct?
All one person or group really needs is 51% of the total bitcoin supply to have full control essentially?
no, a 51% attack is another thing. That consist in the ability of rewrite a significant number of blocks, allowing a double spend. In order to do that you "only" need the 51% of the hash power for a certain period of time (depending on how much you want go in the past). In the previous reply I was talking about the control of consensus.
Ok, I had a feeling it was but wasn’t exactly sure. I thought maybe they were maybe both co-related somehow.
