Respectfully, nothing about that applies to a laptop. This has been well proven over the years, that with good forethought and making parts available laptops can be highly repairable.
If that was the case we wouldn't be allowed to replace AA batteries.
I know quite a few non-techies who replaced their phone screens themselves. That’s been unexpected and impressive to me. Honestly, you can get unlucky, but in my experience, electronic components are surprisingly resistant to abuse.
Sure, if everything is soldered or glued down it‘s intentionally hard to self-service, but that’s also down to your consumer choices. There is nothing inherently unserviceable.
