Amazon has had this store open for employees to use for some time. Think of that time as a massive bug bash hacking project where really smart people are encouraged to try to find ways to wreak havoc with the system. There are undoubtedly attacks still to find but Amazon is definitely not being clueless about this.

They likely have people watching the cameras full-time and will just report you to the cops if they see sleight-of-hand, now with identification and an address since you have to show your Amazon account when walking in. This is probably forever tenable to the bottom line since they're eliminating cashiers and security folks aren't paid that much more than cashiers anyway.
There's also probably a healthy amount of resolution and numerous camera angles that it'll be impossible for your face to not be picked up. Even using a fake account, you're still likely to have something Amazon-related installed on your phone that can be traced back to a telecom account.
And really, none the effort to avoid getting caught/traced is worth it to steal some bags of chips.
