Bitcoin is functioning just fine, what are you talking about?
Sam Bankman-Fried is not registering his coins to my coinjoin coordinator. In fact. I do not even run a Coin Join coordinator. What in the world are YOU talking about?
Your questions are based on the false premise that a coinjoin coordinator can exclude someone from the blockchain, so they don't make any sense.
Your question is based on the false premise that I am running a Coin Join coordinator, so it does not make any sense. Also. Your previous question is based on the false premise that I was saying Bitcoin is not functioning well too. Does not make any sense to even bother answering properly either of them.
If no more valid transactions will ever be possibly constructed with the 'vigilantes deciding to take justice into their own hands'. Then obviously what you will need to do is make it possible to function again.
Okay fine, go ahead and tell me how obvious it is to make coinjoin coordination work without banning the vigilantes: How do you make the coinjoin transaction valid if you don't have a signature from all of the inputs?
I think you need either glasses or sleep. Or both.
