Honestly I would argue it doesn’t matter in either case.
If it is about possession, there just isn’t enough of a negative effect from allowing someone to look at that stuff for another month or so to justify serious infringement on rights without a conviction. The abuse has happened, and a single individual looking at it some more won’t affect things much. And after an actual conviction they’ll just be in prison, or after release you would have a justification to monitor at least their own internet traffic.
If it’s about production, the internet traffic isn’t likely to be the problem. Someone sexually abusing children isn’t likely to stop just because they can’t put it on the internet anymore. At that point you’d rather need to keep them away from children in the first place.
I’m confused too, self checkout is the best thing ever, no social interaction and pretty much equally fast, while allowing for more checkouts in the same amt of space. Though tbf only if done properly. One store here started having them like 10 years ago and there was like a 10% chance each item that you’d have to call over an employee bc the scale didn’t work. Haven’t had any problems with the ones i encountered recently.
