Fair point. It's not necesarily the case that you'd see extensively P2P nodes. But again, a distributed protocol based system would allow for local supernodes, competently administered, to exist.

There's also the issue that client nodes, under any model, also require security updates and practices. The universal P2P model really isn't far from that, and certain auto-updating models seem arguably preferable to present offerings.
