I disagree, if all miners agree to not include a transaction or type of transaction in their template, then that transaction never gets included no matter who mines it.
If, however, a miner with enough hash power and incentives includes such transaction once they win a block, it gets included.
That is I guess at least theoretically possible but objectively not currently happening and miners have every incentive to include them as they can extract extra revenue from the MEV opportunity this presents. In order for that to theoretically happen you have to assume every miner will be economically irrational.
Most miners and thus most hash rate currently accept out of band transactions. There are collective out of band systems like the mempool accelerator and mining pool specific ones such as those by Mara and ViaBTC.
Agreed this is not currently happening, which is why OCEAN was established to attempt to change that.
We also should not root for a world where miners can band together and block transactions as that means uncensorable money is gone, and that’s the whole premise of BTC. If miners hate me for whatever reason and can band together to block my transaction, then BTC has been rendered pointless. This is the very foundation of freedom money.
Bitcoin is a consensus network, if we have consensus to ban you, you are banned. 😂
