I don't see how this is any different than the bog standard "encryption lets criminals and scammers the ability to exchange goods and services anonymously.". Should money/txns be fundamentally track-able/examinable/un-encrypted but your private data/messages not?
Surely this contention is something you also consider -- care to expand?
