Well, I suppose my argument does turn on the scope on which you consider each of these 10 points.

My presumption is that, as nation-states are deprecated, coordination between them will have to take the shape of sufficiently decentralized technology that the "networks have the ability to vet and ignore" portion becomes a local and voluntary process.

And - probably an area where reasonable people disagree - it's the (real or perceived) authority that makes it possible to "be used for evil"; if there is no badge and gun, and each message (broadly considered) is to be considered on its own merits (both for its truth and its persuasiveness), then I think that corporate propaganda just lands in the 'ignore' (or even 'spam') pile.
