Can’t wait for the first “scan this code to verify” scam that takes you to a mobile Chrome 0day

Or you could send them to download some spyware/adware Play Store app

Couldn't any exploit possible via that pathway also be executed based on a link? I don't see how a QR code makes the situation any worse.

Users are habituated to clicking links (mostly from their email) as verification, too. QR codes get a weird amount of hate for something that basically amounts to a hyperlink you can transmit through meatspace.
