That seems about right to me, for the authoritarian mindset I mean.
After all, why would you use PGP unless you have something to hide from
MI5? And of course if it's banned, the bad guys won't use it either.
Just like all the criminals who handed their pistols in when they were
banned.
The guy's a typical politician, spouting whatever ill-considered
nonsense that might win him votes or a few % in the next opinion poll.
He probably just assumes it will be someone else's job & problem to make
it all work somehow.
