Why would having them available be a bad idea?
We need some kind of ID card to interact with most aspects of society (get a job, etc.) and right now the only universal one is the Social Security Number, which we rely on for all the wrong things (and it’s not like you can change that number when a stalker gets ahold of it).
In many situations they’re also useful so that people can know who you’re not (homes for battered women, etc.)
I agree that we should have a level of civility owed to us even without the existence of an ID, but that’s a civil rights issue that’s far beyond the scope of a freely available trustworthy source of identification.
