Why is discrimination necessary? If it was necessary I would presume we need a fork to make this consensus. This is the same type of thing you would have heard from the State if we gave them an option to help design the new system. "We need to have the authority to stop bad TX." However, here, you're just putting bad TX on a more exploitable and longer-term more costly location, UTXO set. Costly for yourself, as a node operator. There is no option on the table to make Bitcoin purely monetary, you get that right? That's gone. We already added features, changed consensus.
