Right to repair isn't "obligation to repair devices yourself", or "force manufacturers to redesign hardware so repair shops jobs are easier".
It's about preventing certain business practices that hinder the repair industry. Like when Apple forces their suppliers to not sell components to anyone but them.
"Component level repair" is a thing that's done today. It involves replacing individual components on a motherboard with a microscope and soldering iron, special equipment, and smart and well-trained people. That's what Rossman does regularly on his Youtube channel.
But even if you have the skills and tools to replace a tiny burned out IC on a motherboard, where do you get a replacement? Apple doesn't allow suppliers to sell them to anyone.
I don’t think your first sentence is accurate - there is no single standard definition for right to repair, and I have absolutely seen people saying that right to repair includes an obligation for manufacturers to redesign hardware so repairs are easier. I’ve also seen people say it’s only about allowing schematic access and nothing else. I’ve seen people say it includes unlocking bootloaders. IMO this is one of the biggest problems with the right to repair movement: the goals are fairly poorly defined.
Louis Rossmann made a video giving his definition, which is that parts are available. However, that is only his definition, there is still broader community lack of focus on what it means.
Some people think it means that Apple must make their products easy to repair. Others think it means Apple must every single chip available for independent purchase. Others think it means Apple must only make available the parts that they would provide their AASPs with (only finished boards and displays, not individual chips).
