Then the store closes, then you get a food desert.
Restraining a shoplifter could lead to liability issues for the employer. For example, if the shoplifter injures the employee, there's a workplace injury that goes on the OSHA record, you have an employee who is out for some amount of time, it could increase insurance rates, and it could lead to the employee getting shot if the shoplifter were particularly violent.
Additionally, if the shoplifter gets injured, they may sue the store for the injury they sustained.
Most of the US does allow a citizens arrest to be performed.
In Germany, you'd fire the security if they wouldn't go after thieves. Also, there are no liability problems... But then, people with guns or knifes are very rare.
Stores will use cameras and AI to build a comprehensive case against someone or group and then notify the police. That will be enough for a warrant etc...
Probably a startup or two in this space. I am sure home depot or CVS will invest in your series A.
In Costco's favor, they don't have a lot of valuable things that you can just walk with that aren't just a cardboard voucher.

They hire security personnel, but people figure out that a) even when security catches you, they are not allowed to restrain you and b) the police do not respond to shoplifters (in certain jurisdictions they are not allowed to.
The stores are responsible for the cost of missing inventory - they credit it back to the manufacturers. Stores already run tight margins, so this cost ends up getting paid by reduced headcount at stores (except for security, if it's bad enough) and directly in prices.
And this is in the grocery space, where there's very little secondary market for the stolen goods!
