This is, increasingly, the solution to the perceived threat of shoplifting. Put everything behind lock and key.
Of course, that kind of set up costs money. And then you need more staff to run around with keys and unlock everything any time it needs to be sold. Patrons find this annoying. Businesses find the security+labor expensive.
The solution to this is vending machines. So in the end, we turn every Walmart into a big wall of GACHA machines.
