I think you should start monitoring your level of ego.
I'm not displaying any ego, I'm educating people how Bitcoin works.
If Bitcoin can not FUNCTION any more due to an issue that NEEDS to be addressed. The issue will be addressed. The 184 Billion Bitcoin bug should tell you something.
Bitcoin is functioning just fine, what are you talking about?
Same for Coin Join coordinators. 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 to make coinjoin coordination work without banning the vigilantes: How do you make a transaction valid if you don't have a signature from all of the inputs?
