Bingo. And if you want bitcoin to be a blockchain, you have to permit entries in to the chain. And if you accept entries, you must accept anything that can be encoded and follow consensus rules; no matter how tight those rules may be, you can always choose to encode CP. Playing the “take away useful features to stop CO” game is a cat and mouse game for morons or those wishing to make bitcoin eventually useless.

Exactly. The same way the guns don't kill people.
