I do miss the point, indeed. The point I miss is that the problem is people who don't want to accept the inefficiencies of a decentralized network and its inevitable role as a data later, but want to meddle with it, causing unintended consequences, because they place themselves as arbiters of truth.

The mempool issue isn't FUD. If you have a different mempool than the mining pool's, then your fee estimation is less accurate. That should be fairly straightforward to grasp.

The more you try to censor dataonly transactions, the more you push them to transform into forms that are indistinguishable from regular transactions, and then it'll be even worse for all of us, because they'll bloat the UTXO set with millions of unspendable UTXO.
