When you buy something, you do have pretty broad rights to repair it.
The problem is, they are becoming less and less effective.
If you have no documentation or repair manuals, then it's harder to fix. An authorized repair site might know what error code 59276 means, but do you?
Apple famously started using a pentalobe screw, seemingly for the goal of making it harder for people who aren't at authorized service centers to carry out repairs. If a company uses non-standard parts when standard parts would work, this makes it harder for you to repair your own items.
In the pentalobe case, third-party vendors sprang up to sell the specialized screwdrivers, so it became less of a barrier. But imagine if the new screw were covered under patent that prevented substitutions .. and only authorized repair centers could buy the correct screwdriver.
Companies are using their rights under other laws to make it harder for you do to your own repairs. For example, farmers are turning to foreign hackers because farm equipment companies use the DMCA to prevent farmers from using anything other than authorized repair technicians from fixing the equipment. This equipment is increasingly reliant on DMCA-protectable software.
As you saw in this case in Norway, Apple wants to use its trademark power to prevent people from buying parts which would otherwise be legal
Are there any requirements would you force upon Apple in order to ensure that people have a reasonable ability "to repair any item they own or pay anyone else to do it?"
Make not mistake - it's also well-established law that the government can force companies to sell to people they might not otherwise want to sell to.
