In fairness to their argument, I have actually seen serious consequences from the mass theft of baby formula. When I worked in a children's hospital, we had babies coming in with malnutrition problems because they required a special formula that was completely unavailable. The parents couldn't buy the formula because it was out of stock at every store they were able to get to with the transportation and time available to them.

People stealing massive amounts of formula cause massive problems because the specialty formulas are hard to find to begin with, and these people are clearing out store shelves to sell it overseas.

The wealthy parents that live in nicer neighborhoods with fancier stores and fewer problems with shoplifting don't run into this issue. It the poor families in food deserts that are most impacted by this kind of mass theft, and they're the families least able to work around it by just going to another store to buy it.
