> the government has the mistaken belief that their back door will know the difference between the good guys (presumably them) and the bad guys

This is a very good point, and in the recent months we have been witnessing that people in government, or aiming to become the government, are definitely not the good guys. So, even if what they are asking would be limited to just governments (which it wouldn't), they can't claim they are the good guys anymore.
