> Like that would sound nuts if we applied it to other things - e.g. "take away the professional license of a mid-career pilot/surgeon/schoolteacher/engineer because he was drinking on the job and his life collapses".

The analogy is closer to "take away their ability to get any job" and then it sounds even more harsh.

> Various people can't drive because of e.g. visual impairments, age, poverty, etc. - I find it an ugly juxtaposition to be asserting that we must allow people with DUIs to drive because otherwise their lives would "collapse" to the same point as those other people who can't drive.

If you can't see well enough to drive, then life was unfair to you, and you can often get help with transportation that isn't available to someone that violated the law. For age, if you're young then your parents are supposed to care for you, if you're too old to drive you're supposed to have figured out your retirement by now. For poverty, you kinda still need a car no matter what, that's just how the US is set up in most areas. And it's not ugly to make the comparison to extreme poverty, to say that kicking someone down to that level is a very severe punishment.

> must allow

I wasn't saying what we should do, just that turning up the aggressiveness has serious unwanted consequences.
