How often have you needed to repair a MacBook? The enhanced repairability is basically insurance in case of a fault. Compared to a MacBook, or insurance for a MacBook, this insurance is overpriced. As for the environment, the power consumption + larger design with extra parts to make it repairable + how few people ever buy parts makes this a virtue signaling wash.
In the 15 years I've known her, my wife has needed to repair each of her 3 MacBooks at least once (One of them twice). In the same time, I've had to repair one Gigabyte laptop. The second Gigabyte that needed repair, I trashed and just stopped buying Gigabyte. That's the problem with Apple. They're build quality isn't that great, but you don't have an alternative.
I have been buying Apple hardware since the early 2000s (the first thing I own was a 1.5 Gen iPod) and there is almost no product that didn't get an issue. Very often developing early in life because of bad design/engineering. I think the most reliables have been iPhones but that's only if you don't count annoying battery swap and other minor repairs that came for aging (like port replacement).
But they look good and make people feel good, so they get bought.
That's definitely the problem with Apple, if you could run macOS on any machine, they would lose market extremely fast.
