I think he understands it&#x27;s possible to ban it, it just won&#x27;t work for the cases that matter.<p>There&#x27;s a deeper problem with banning encryption of any form (e.g. &quot;strong encryption&quot;) that an encrypted file can be made indistinguishable from random data. If the police or any prosecutor will never be able to tell that a chunk of that was strongly encrypted (technically feasible), the law will never work.<p>And then there&#x27;s the sheer absurdity of the idea, which the comparison banishing starting fires doesn&#x27;t capture.
