Not everyone uses Macbooks. There are plenty of laptops with easily replaceable batteries and sane keyboards. Not even talking about real computers, where you can replace everything without any tools.
However the popular "ultra" books and similar have to integrate more heavily to get close to 1". Even fans become hard to replace. Often there's no dimms (so you can't replace or add ram), even storage can be on the motherboard.
They are close to disposable unfortunately.
is it a consumer grade or corporate model?
