Have lots of layers, accountants, execs, and a few surgeons in the extended family, especially on my wife's side. Most of them use Macs as their personal computers, and some of them have already upgraded to M1 and M2 mac pros.

Lot's rich people out there, bro. Some of them probably suffered to adapt to Mac OS after years of using Windows, but since every new version of Windows is now a different OS from the UX perspective, they all adapted themselves to Mac OS, because they wouldn't want to be seen in an airport lounge or an expensive coffee answering their emails in plastic Samsung book.

Also, most people never upgraded their laptops, this is simply not an important selling point, and even less in the premium segment. Repairability? From the user's perspective, It is repairable, they have Apple Care, and they drop their broken laptop in a counter, and sometime later they collect a functioning laptop. And why they wouldn't like the hardware? The CPU is fast, it hardly ever heats enough to spin the fans, the screen is great, the keyboard now is good enough, and the touchpad is still probably the best one on the market.

Your plenty of reasons don't seem very solid to me.
