Maybe, you're not replying to the main argument put forth in my note though: do you agree that changing consensus on Bitcoin requires hashpower and that without it nodes cannot do much?
I think I agree. Here's what the hashers did though. Core increased the op_return. Clearly not good for Bitcoin. Hashers implemented it. Thats a work of a fairly small network of individuals. Thousand of nodes then request to roll it back + minimise the non financial data. Hashers deny that. So if the changes in consensus are dependent on centralised miners permission then Bitcoin is not really permissionless or decentralised. And if the hashsers are happy to have high op_return which is causing problems for nodes, the nodes have the right to find new hashers which align with the wishes of these nodes. And that's what is happening.
