I've considered this response also, but I believe Satoshi was responding to Dan Larimer. He later became a founder of the scam EOS, and is probably a billionaire because of that scam. Not certain of any point I'm trying to make. Maybe just to be careful of someone having the last laugh if we engage a bit too harshly?
Try this “If you don't believe me or don't get it, I don't have time to try to convince you, sorry."

Agreed. It’s not about having the last laugh. The question was about someone that understands perfectly but still disagrees. When there is clear and effective communication but no agreement, then all you can do is walk away. You can’t coerce agreement.
