The inevitable result of government setting prices is some combination of:
1. shortages
2. gluts
3. black markets
It doesn't matter what your or my opinion on it is, any more than having an opinion on F=ma. The Law of Supply and Demand is always in play.
There are thousands of years of history on this.
This isn't government setting prices. It's just government outlawing a certain form of price discrimination. It's forbidding sellers from transferring consumer surplus to themselves by charging a higher price to customers that would be willing to pay a higher price for the same item. But the item is still available to buyers that wouldn't want to pay the higher price--at the lower price. The grocery stores aren't going to raise the overall price to compensate for losing the ability to price discriminate: that would result in less profit for them. Whether they will try to find other ways of increasing their profit over what they get when every customer pays the price that's equal to their marginal cost, is a different question.

I.e. the government is regulating prices, yet another attempt going on for 4,000 years of trying and failing to repeal the Law of Supply and Demand.

Allow me to explain how prices are set:
Consider an appliance store. They want to sell refrigerators. What do they do? They have 3 refrigerator lines - the stripper, the midline, and the lux. The purpose of the stripper is that is what they advertise, to bring customers into the store. The purpose of the midrange is to upsell those who come for the stripper, as they think the extra features are worth it. The lux is sold to the wealthy customers who just want to buy the best. (Not having a lux is means the retailer is throwing easy money away.)
The moneymaker is the midrange.
You'll see the same thing in the grocery store. The store advertises the price of milk, which is likely at below cost (called a "loss leader"). People come to buy the milk, which is always on the back wall of the store. The customer has to pass by all kinds of things to get to the milk, and they'll buy it. The most overpriced stuff will be next to the checkout line.
Cheeses come in cheap, midrange, and lux, too.
There's been an extensive amount of research on exactly how to set up the store to maximize profits, which is necessary as grocery stores have razor thin margins.
BTW, the article is paywalled. I have no idea how a grocery store is going to adjust prices at checkout, as the prices are marked.

Many stores are rolling out electronic price tags on the shelves, which can be rapidly updated wirelessly [1]. They could probably do the price adjustment there. I'd assume they wouldn't want to make it too blatant, which would be a challenge.

If it adjusted the prices as someone approaches, I suspect customers would soon notice it.
I'm not going to order food at a restaurant if the menu has no prices on it, even if I'm a zillionaire.
Somehow we did just fine without real-time per-customer price discrimination.
As I've pointed out elsewhere in this thread, it's been going on since the first fruit stand thousands of years ago.
