Isn't this because manufacturers are actively hindering repair shops? It's both the result and the cause of the manufacturers' strategy. No schematics, devices built without taking repairability in mind and very expensive parts or parts that come with caveats.

Making longer warranties is always welcome but it won't help as much, because the vast majority of repairs aren't covered under warranty. I'm guessing that most repairs are due to user error than manufacturing defects thus not covered under warranty.

This shouldn't be the case. Reducing e-waste and thus doing everything possible for sustainability should be the priority here. I've found myself many times in a situation where a perfectly working device was damaged, or just stopped receiving software updates and had to be decommissioned because of security concerns, and this is not only limited to phones.
