I think the advantage this time around is information access.

That and repetition. Prominent bitcoiners & cypherpunks are in my view more accessible today than privacy oriented email advocates. They put their money where their mouth is. There was no money in email. Bitcoin is a money protocol.

So if prominent bitcoiners keep preaching directly to people, and distrust in legacy media keeps building, the outcome might differ. More people may be looking in running their own nodes.

I never ran my email server but probably would’ve if I didn’t discover the convenient route first. However, I do run my own node.
