The problem with that is that it operates from a wrong idea of how to set prices for a product. From first principles, you make a widget, figure out how much it costs to make it, including your time, then add some amount of margin on top, and you have a business. That is incorrect. No, you have product, and then you just make up a number based on circumstances. If you're lucky, the price you manage to sell your widget for is above what it costs to make it. If you're not lucky, it isn't, and you have a sale, and lose less money than if you didn't sell anything. However, if you're lucky, you sell your widget for way more than it costs to make it, because of branding, aka luxury fashion brands. The numbers though, are just made up. That's the trick of capitalism. You just... make up a number! Once you understand that, the world starts to make even less sense than it did before. If pricing were cost-plus, branding and timing wouldn’t matter, and empirically they matter a lot.
You're describing what happens in uncompetitive markets (or for status goods, which have inherently weird behavior because they're a signaling mechanism that relies on waste and artificial scarcity as a mechanism of operation, but also inherently nobody actually needs them).
In an ordinary competitive market, margins are thin because sellers are fungible, so charging slightly less than the competition results in a disproportionate increase in sales because customers are just choosing the lowest price, and then sellers keep lowering prices until margins are thin because it's more profitable to get a $0.05 margin on a thousand units than a $0.10 margin on a dozen units.
