I see your point, however I have to politely disagree:
The naive solution to the problem you described would be to simply broadcast every email to every possible receiver. And in fact, I believe this is how bitcoin actually works (but I am happy to be corrected).

Exactly. And to every possible relayer too! Assuming we've dealt with the SMTP assumption of hostname = final delivery point.
You might have read the parent reply before I finished it (I have a bad habit of editing after sending replies, sorry).
As email works now, you'd receive duplicate emails, right? Easy to deal with if you wanted to, but Bitmessage works like that by design and assumes duplication as part of the system.
So, if your solution to the centralization problem is, literally, for email to become more like Bitmessage/Bitcoin... then what are we arguing about? :P
