I am not trying to give you a hard time, but you are just missing the point of this thread.
Storing illegal data in bitcoin transactions is something that has not even been considered yet by law enforcement and such.
I am pointing out that this will absolutely be a problem in the future for Bitcoin, but it will not be a problem for Grin.
The point is that, regardless of any privacy concerns, it is safer and more efficient to have as little public data as possible.
The idea of permanent, public data is just a threat vector that has not really been considered up til now. It has always been assumed before that illegal data can be taken down. But if you encode the data in your financial system. You can’t take that down unless you take down the whole financial system.
Grin is just better at doing one thing well.
