Usenet and IRC, which he says he loves, were extremely toxic. 4chan is the closest thing to the flavor of that world. Free speech is just something you have to go all in on if you want decentralization. However, Usenet had bad spam problems unfortunately that led to its downfall, IMHO. Same goes for email. Spam largely killed independent operators sending email and led to centralization under Gmail, etc.

What if someone could create some sort of system that would be geographically localized in order to reduce spam? This was sort of how things worked in the BBS days.
