attacking Bitcoin can be done as a self sovereign act.

that doesn't mean there aren't social or economic consequences.

Marginal improvement on miner efficiency should be a priority to whoever cares about mining decentralization.

Also, this is a problem for miners, not node runners.

So large mining operations can have high data bandwidth connections to each other, thereby having more time to work on a block than a smaller miner that may be part of a smaller pool say running off a gas generator in South Africa or helping sustain the energy demands vs energy supply inefficiencies of some power grid somewhere remote with much slower internet connectivity.

That direct connection vs node to node gossip to eventually some small miner can mean whole minutes of time that the bigger data center style miners have working on a block that those smaller miners are still hashing on the old block.

BUT when the trade off is preventing sovereign node runners from setting their own mempool policy, it doesn't seem like individuals are going to like that regardless of the downstream effects
