I don't think people who are blasé about shoplifting have thought through the implications of this sort of theft becoming rampant.
The kind of losses this causes to a business are unsustainable if it is more than a one-off.
Either the businesses leave the areas where this occurs, immiserating everyone who lives in the area, or stores transition to being set up like inner-city liquor stores, which depresses business anyway, or the law changes to crack down on this behaviour, either through letting private security off the leash in how they handle this, or by dropping heavy sentences on people who are caught.
Mass shoplifting is totally unsustainable as a regular occurrence.
