Does this also mean only using "standard" parts? Or does the manufacturer have to over-produce the parts for, lets say 7 years, and then warehouse and ship those parts, probably multiple times. Or keep a low rate production line running for 7 years? What happens to the parts that don't get used? Are they scrapped?
That "what if" cost is going to be built into the cost of the laptop. Repairability doesn't always keep the cost low. The purchaser will definitely have to foot the cost otherwise it isn't sustainable.

Why not? I don't understand how it's legal for manufacturers to produce absolute trash that can't be replaced and will just end up in a landfill. I think 7 years is far from enough, but because computers evolve quickly maybe 15 years is ok. For the rest of electro-mechanical goods, 50 years should be the baseline.
If a car or fridge from 50 years ago is still working with proper maintenance, that should be the minimum to be expected from products released today.
Repairability definitely doesn't keep the costs low. If it was cheaper and easier, it wouldn't have to be regulated. As for supply chain management, companies that get that equation correct are going to benefit. Which is exactly how it should be.
We define the rules of the game and companies that can best implement those rules will succeed. That is capitalism.

None of that is relevant in this context: The parts are available, but the laptop is designed and built such that the alone keyboard cannot be replaced.[1]
[1] Not sure if this is possible on that specific laptop, but with a steady hand, a tiny drill, maybe a magnifiying glass too, you can maybe drill out the rivets, then replace the keyboard, then either re-rivet it back again or tap very tiny thread into the laptop and use screws.
