AND... they would pay more if they need a private mempool to do it. disincentives. You can run circles around this all day, but the reason we're gonna go 1000x on OPreturn spam in the next few weeks, is solely because of Bitcoin Core choosing "bitcoin is a database" as the hill to die on. Shitcoiners are sharks and yall are choosing to chum the water at the beach.

Why would they have to pay more? That's just not true. Again you're wrong. Highest fee is highest fee. It's not more expensive because you go to some other nodes mempool.
