There is a difference between trying to convince the right people and wasting time on the wrong people.

People who are not familiar with and do not want to educate themselves on certain concepts, are not worth engaging with at this point (but may be in the future).

Satoshi did the same thing. There was a point in the early days where he gave up on trying to convince people.

Cypherpunks write code, they don't argue (too much).
