"I find this thinking to be a bit bizarre. Right to Repair is founded in property rights. The entire premise is that when the end user buys equipment it becomes their property and they (should) have the legal right to do whatever they wish with their property."

The owner can do whatever they want to it, but that's not the issue. In order to repair it, you need the seller to make available schematics, diagnostic equipment, proprietary tools, and a parts list, and an agreement that the parts manufacturer would sell those parts to a third party customer.

As it stands, the owner has the right to do whatever she wants with the item, but the RIght to Repair is mandating that the seller provide specific accommodations.
