That’s not irrational. It doesn’t cost any more to make a lemon cake than a chocolate cake but a lemon cake is more valuable to me because I don’t like chocolate. Perfectly rational.
(otherwise good point)
But objectivly proofing it, would require a very complex bio-chemical anaylsis of his digestion and neurological system as well as a deep psychoanalysis. Interesting research probably, but not necessary for determining that objectivly lemon cake has a higher value to him, because he simply likes it more.
Acting against what makes you feel better is rational. I don't think that's controversial.
If you're a cake mix company that only sells chocolate cake mix, switching up production to include vanilla has expenses all by itself. You now have to manage extra ingredients in your supply chain, schedule time to switch production and all the overhead and downtime in doing so...and your factory-to-retail logistics chain is now both more complicated and split between the two products.
If you retail cake mixes, why would you dedicate capital, storage, and shelf space to something that sells at one ninth the rate?
Etc.
Given that premise, it’s still possible to value one less than the other.
Given another premise that wasn’t in the comment… we’ll you can still value one less than the other but so what?
If I never paid more than production cost + some "reasonable" markup I wouldn't be able to buy a lot of things that I enjoy.
A smart business sells things at roughly the price that people value them. A key job of the business is making that cost them less then the selling price.
Since some people are willing to pony up significantly more for the black, they can offer the non-black at a slightly lower cost than they otherwise would, which means they can sell MacBooks to a segment of the market that would otherwise consider them out of reach.
Any time virtually the same thing is offered at different prices, you can either complain that it's unfair one target segment has to pay more... or realise that the flip side of the coin is that less price sensitive people subsidise lower costs for more price sensitive people -- which could seem completely fair depending on ideologies.
If you're a hardcore capitalist you see it as a way for the manufacturer to expand their target market without sacrificing profitability. If you're more on the left you see it as taking from the rich and giving it to the poor, without having to resort to coercion.
Each lens/sensor theoretically costs a very similar amount of manufacturing cost to include, so theoretically if your goal was to give the customer the best value on a cheaper 2-lens phone, you would want to give them the two most used lenses: the normal wide lens and the telephoto lens.
However, Apple gates the more-desired telephoto lens to the Pro model, because it needs to balance the significant price increase with the reality that there isn't much of a manufacturing cost difference between Pro and non-Pro phones.
So, it's a market segmentation based on some desired features.
I disagree with the idea that there's any sort of a positive "flip side" to this strategy from the customers' perspective. This is how profit is maximized. Apple could sell the iPhone 13 Pro for less money and still make a profit, but they know that customers of certain income brackets will pay over a thousand bucks for a phone.
If the iPhone 13 had a telephoto lens instead of the ultra-wide lens, and the ProMotion display, the iPhone 13 wouldn't cost a dime more to manufacture. In this configuration, there would be very little reason for most people to upgrade to the Pro model.
I.e., if the 13 and 13 Pro were nearly identical, yeah, there'd be no reason to upgrade to the pro model, and so Apple, being sensible, would instead offer one model. And the price of that one model would fall somewhere between the 13 and the 13 Pro; meaning that some people who can justify paying for a 13 now would not buy one at all (and you're not extracting as much as you could from those willing to spend more as you could by segmenting it).
By segmenting it, though, the (obviously highly inflated, still super high margin) cost of the 13 is lower, and Apple can put the cost of the 13 Pro higher, because each segment now has its own point of highest profitability (the point where price * number of people who will purchase it at that price is highest; generally the higher the former the lower the latter).
This is also why some graphics cards, for instance, were all made to the higher end specs, and then had chips locked away, damaged, or etc, just to create market segmentation. Even with the fixed margin costs, segmenting the market allows the company to maximize profit, but by doing so it also allows the lower segment to come in at a lower cost than if they were trying to maximize profits with a single segment. It's a "win/win" from an availability/affordability of goods and a corporate profit maximization perspective, even if it feels stupid and unfair to pay extra for the high end card, or be purchasing a 'crippled' card.
I believe this choice is because of another much more desired feature: Night Mode™
IIRC It works by overlaying and processing the two images from the ultrawide and wide angle lenses. It's why Night Mode is limited to the wide angle lense, and not available on the ultrawide, as the wide angle lense doesn't provide enough coverage for the ultrawide to produce a Night Mode image.
If Apple included only wide and telephoto, then Night Mode (As currently implemented) would be limited to the telephoto images, which would be a lot less desirable.
I think it would be irrational to value things based on how much they cost to make. The rational thing would be to value something based on utility to you. Why should you care how much it cost to make, unless you have as an alternative the ability to make it yourself?

Especially SWEs who work in products w/ zero marginal costs shouldn't complain about market value of a product vs. BOM costs
…especially if you consider that even product that don’t end as ‘vaporware’ are often immaterial.
They’ll joke about the uselessness of philosophy, then argue the differences between == and ===.
It’s really no surprise from there that they’ve happily embraced “fiat isn’t real” conspiracies and seek to improve that terrible state of affairs with a zoo of inscrutable algorithm-money.
Just as one example, I've been using a work issued macbook for over a year and I still regularly send the screen brightness or volume off the rails because I lightly rested a finger on the stupid touchbar. But hey, it looks cool to use the volume slider!
More broadly, look at any discussion of web fonts here and you’ll find three suggestions to give everyone „three fonts and be done with it, screw those designers and the strange feelings I get when I see them on their skateboards.“
People are boundedly rational. The client base purchasing the black enclosure valued it for a few extra hundred USD relative to other things they may choose to spend their funds on.
People are irrational, they value things that don’t necessarily cost more to make, and sometimes even the fact that they need to pay extra for it, is in fact why they want it.
