You only get ID’d for alcohol if you look like a kid

Depends on the place

And when you do get carded, they look at your license, check the date, and hand it right back.

This is true for most places. There's nothing stopping a creep from memorizing more than they should, but that's of course an edge case.

While uncommon, there are places such as casinos that take everyones ID and use an ID scanner to add them to a local, or not local, database. Places that do that really are no different from websites that want to ID. Except with a website you'd provide it once, and at those facilities you have to have it scanned each time you go in.

But a blanket request on everyone to ID themselves by default is just not the way.

I couldn't agree more. It's a terrible idea and is going to spell disaster for many people. I am not arguing we should have websites collect IDs, my argument is about whether age verification on websites should exist in any form, even if it's securely setup. Many people here think age verification is strictly a problem of parenting, and I think that's an absurd argument.
