I did hear mechanic out, but I also listened to other people too and worst of all thought for myself.
Information theory is very clear. No matter what Mechanic or anyone else does someone will find a way to sneak data he and Luke don't like onto the chain.
It is a foundational concept of encryption that a good encryption algorithm output is indistinguishable from the output of /dev/urand unless you know the type of encryption and have the key. They only way they can win is to eventually transition to a whitelist of pre-approved plaintext transactions. Want 11 of 17 multi sig but they didn't whitelist it? Too bad. Want privacy on chain? Too bad. This is not a hypothetical, knots blocks whirlpool transactions.
On top of that, remember that this is all about mempool. They are not and were never going to not store the exact same data in the chain on their node. They can't or they'll fork and suffer the same fate as bcash and other minority forks.
What exactly are they trying to accomplish? They want every bitcoin TX to be something they can read and approve of or deny based on their personal rules. That is some CBDC shit. If I wanted a CBDC I would use one.
