> Local governments have no desire to spend resources negotiating SSL/TLS with every single smartphone in their area when things explode, rivers flood, or people are poisoned.

That's one horrible argument, though. The cost of a text-based protocol on ethernet, over TCP greatly outweighs the cost of the encryption process.

Yes, of course encrypting things will increase computational requirements yet the cost is negligible in comparison to the problem being solved (stopping the trade of personal data).

It's hard for me to associate a privacy champion with these statements.

I can also recommend this one, which - strangely - turns into a privacy/security discussion for the second part of the talk.
