I think the biggest issue here is there's not a colloquially accepted understanding of what Right to Repair is.
What you're describing, and I agree with you, is what many legal right to repair advocates are fighting for.
However you'll see many people conflate it with easy to repair and easy to get parts, or repair without voiding warranty. Which IMHO should be separate talking points, but alas, they're all jumbled up when these discussions happen.
It's also why I don't think right to repair will please most people. Because the scenarios you described are limited and outside what most people are thinking e.g home repairs of cell phones
