That would be true if it were the only solution, but it isn't. The important things are stored on a server/cloud, and data is otherwise backed up properly, right? Because if it isn't, the issue isn't Apple but it's the data policy. If it is, then you can just swap in another machine while the broken one gets fixed. Almost all lease contracts dealing in the hundreds of laptops account for having some hot spares on site at all times for just these situations.
Indeed, that's what my IT department does with our Lenovos. Maybe they're repairable, who cares? Why pay an in-house IT worker a high salary to do silly things like swap keyboards and drives, when it's cheaper to just swap it out and ship the broken thing somewhere else and have the leasor/OEM deal with it?
