So connecting to many nodes just because we can and it's not technically
prevented is bad for the network and creating systemic risks of failure,
but relaying harmful double spend transactions just because you can and
it's not technically prevented, is good for everyone?

If someone did enter into contracts with miners to mine certain
transactions, and had a guarantee that the miners would not build on
previous blocks which included double spends, then they would only need
contracts with 51% of the network anyway. So it wouldn't really matter if
you were a small time miner and wanted to run full-RBF.

I don't personally see what good this does for bitcoin. Now you are
suggesting that we should prevent a 51% attack by using policy and
promises, rather than a technical solution. How is this any better than us
relying on existing double spend rules which are based on policy and
promises?
