> Though as you said, the stores do not want the liability of guards taking action so they are left with locking everything behind glass and deploying privacy invading surveillance.

Stores have plenty of incentives to engage in privacy invading surveillance even ignoring shoplifting as a factor. If a store saw zero shoplifting they'd still deploy privacy invading surveillance because it's profitable for them to do it right now and it will only be increasingly profitable for them to do it in the near future.
