I think a really simple way to put it is if we didn't have the mempool, it'd be
good to create a free service that got transactions to miners in an equal
opportunity, decentralized, way. A simple flood fill scheme would be a great
way to do that... at which point you've re-invented the mempool.
Nothing wrong with people running nodes that opt-out of transaction
broadcasting, and it may even make sense for such nodes to preferentially peer
with each other. But there's always going to be a need for a scheme like the
existing mempool, so might as well just keep it.
