I think this is our fundamental disagreement. People will burn coins to
encode data, why allow this when there's a better alternative?

Correct, but with BIP70 that key is in the user's wallet and you can
construct transactions on another machine (thus not needing a key during
construction). Right now there's no way to do the transaction construction
on another machine with zero value OP_RETURNs.
