The idea of a supermarket or department store is kinda “new-ish” (on some historical level), right? Like it is a post 1900 invention I think. Before this, most stores were full service. You go up to a merchant in the bazaar, or the grocer behind his stall, with a list, and they go into the inventory to grab the stuff for you.

The innovation of having customers grab their own stuff without supervision was required for all these massive super stores.

We shouldn’t compare the status quo of self-service with some shoplifting to an imaginary ideal of self-service with no shoplifting. We should compare it against the actual alternative of stores bottlenecked by clerks that can only serve one customer at a time (or at least stores small enough that a clerk can watch everybody doing their self-service). You have to pay those clerks!

Stealing is wrong. But some loss is a cost of doing business. People shouldn’t get irrationally obsessed about it, to the point where they think society is crumbling or whatever. Or make LP so annoying that they scare off normal customers.
