There are two reasons this often results in a market failure.

One is when the market is too concentrated. So e.g. when substantially all of the SoCs in smartphones are made by just three companies, none of them have to provide adequate drivers or documentation unless the others do, and then their devices become e-waste as soon as they themselves stop updating the binary blob drivers for newer kernel versions, because the kernels the old blobs are compatible with have published security vulnerabilities. A better solution to this would be to break them up / stop letting them buy each other, but state-level governments have little ability to break up multi-national corporations and national governments have failed to do it, so here we are.

The other is when the rule is to protect customers other than the original purchaser. In many of these markets one customer buys the product new, with a warranty, and then sells it to someone else when the warranty expires. The original customer doesn't care about repairability because all their repairs will be under warranty, and may not even care much about resale value because they're affluent, so the OEM can sell them a device that isn't repairable. But that screws the customers in the second-hand market who need to make out-of-warranty repairs, and it's those who the law is trying to protect.
