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.
> the government is regulating prices
The government is regulating one particular thing that many sellers try to do (price discrimination). But it is not preventing sellers from adjusting their prices based on supply and demand. The seller can still set price equal to marginal cost--i.e., where the supply and demand curves cross--to maximize profit. They just can't extract further profit by charging richer customers more than marginal cost to transfer the consumer surplus to themselves.
> Allow me to explain how prices are set
Spare me your patronizing. I already referred to a textbook on price theory elsewhere in the thread. I know how it works. That should be evident from what I posted above and earlier in the thread.
None of what you describe is price discrimination--nor is any of it outlawed by the law under discussion here. You are describing marketing strategies involving different products--different levels of quality. Of course sellers do those things all the time, and they can continue to do it under this law.
What the law under discussion here outlaws is charging different customers different prices for the same product--for example, the appliance store you describe charging the rich person a higher price for the same refrigerator--say the midline--than the average middle class person. It says nothing whatever about the rich person paying more for a better refrigerator--the lux--than the average middle class person pays for the midline.
As you can negotiate prices at an appliance dealership, obviously people pay different prices for the same thing. The prices at the grocery store change daily, obviously people are paying different prices for the same thing. The guy you sit next to on an airplane paid a different price than you did. The pump price at the gas station can change hourly.
> They just can't extract further profit by charging richer customers more than marginal cost to transfer the consumer surplus to themselves.
The demand curve is different for every customer.
It is fraudulent to charge more than the posted price. But absent that, it's a negotiated price.
BTW, do you also feel it is unfair if a store charges a person less if the store realizes the person is a bit needy?
Just for fun, watch the movie "Back To School" starring Rodney Dangerfield. The funniest bit in it is when Dangerfield (a real estate developer) lectures the business professor on how business really works.
I've run multiple businesses. It's pretty clear that I did not have any power over the customers. I could not just raise prices and "extract" more profit, much as I would have liked to. It's hard to make money running a business. Businesses go bust all the time. I wouldn't pay too much attention to a business professor who had never run a business.

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.
