You're absolutely wrong. There's no censorship in mempool policy. There are plenty of consensus valid transactions that your node doesn't relay out-of-the-box* that a miner can include in a block. 

* It's important to point out that "Consensus valid transactions" aren't always in the best interest of individual nodes and having a mechanism to discourage such behavior is necessary. 

My favorite example is the 2013 White Paper TX which uses bare multi-sig outputs to encode the Bitcoin white paper. (Coincidentally OCEAN's predecessor Eligius mined it). https://mempool.space/tx/54e48e5f5c656b26c3bca14a8c95aa583d07ebe84dde3b7dd4a78f4e4186e713

Go try and relay that same tx on the P2P network today 🤷 you can't, it won't go anywhere because of size and datacarrier rules in modern versions of Bitcoin so most nodes won't forward it on, but you can still go out of band (i.e. like MARAs tx accelerator) -- where's the censorship ?

See? Go back to school 😤
