> There is no "only the government can remove the envelope, if they get permission".

Okay, but now the case you're trying to explain is "there are deep technological challenges and a wealth of historical precedent make me skeptical that we can correctly design or implement a solution that allows only the government or the intended recipient to decrypt the message, instead of only the intended recipient".

To people who think "technology is magic".

And on the other side of the PR battle, the government is saying "Nah, we got this. And if you try and stop us, we're powerless against pedophiles and terrorists."

Adding enough nuance to make your position technically accurate, also makes it abstract enough to be politically useless.
