Agree that bitcoin blockchain is unnecessary, but isn't there some merit in the idea that all major publishers in a juristiction would opt-in to posting to a single chain? Given the potential legal cost savings it would seem to be at least somewhat feasible.

Oh absolutely. But I don't know how much of a "blockchain" that really is depending on how you define it. When I think blockchain, I think miners/proof of work/etc.

Is a CT log a blockchain? Because really what we're talking about here is a signed ledger which may be decentralized but very well may be centralized as well.
