I'd have to spend some time talking about why we need technical solutions to political problems which eliminate centralized targets.

But maybe that already fits under architecture.

When the inevitable question about policing illicit content comes up, I'd say something about how I'm far less afraid of the freedom resulting from decentralization, than I am of the inevitable corruption of centralized authorities. And since central govt has overwhelmingly been the most murderous & destructive force in human history (& we now have clear evidence of govt censorship on major social networks) that seems like the most reasonable position to take.
