I disagree. The lack of repairability has external costs not born by the purchaser or the manufacturer -- more toxic trash unnecessarily added to the environment.
Forcing a particular trade-off on everyone is entirely the point. It's the point of car safety, it's also the point of minimum warranties, electrical emission regulations, safety standards, etc.
It's much more effective and economically efficient to deal with externalized pollution costs with deposits to incentivize proper disposal.
A ton of normal users will simply never bother to repair their own laptops no matter how easy it is, but you don't even have to recycle your own bottles and cans to see the effectiveness of bottle deposits work. Someone will usually come and recycle them for you in any big city.
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.
