Would not help at all.
Any damage from “ethical” shoplifting, if that even exist, significant enough not to be just ignored would be turned on shoppers/clients by raising prices or locking down goods.
That would turn into just damage lower income people.
Yeah, that’s why I wrote “if that even exist”. I can see corner cases where it might be a necessity, but that should never happen in a modern civilized country where medication is free and food accessible to everyone (food banks, kitchens and such).
