The null policy always has more empirical validation because society clearly hasn't collapsed under it. This fact might be the essence of conservatism.
Even if the right to repair were a bad policy, it certainly wouldn't cause society to collapse. Nor would it destroy democracy or cause any other irreparable damage.
Implementing it merely risks a minor decrease in economic efficiency for a few years. The potential reward can last for an unlimited time. And there's a guaranteed reward too: Gaining knowledge on what policies work. We should do it even if we expected it to fail (see also VCs).
I know what you're getting at, and there is something there. However this argument is unfalsifiable.
No society ever collapsed due to policy on repairing washing machines. One could survive indefinitely in a sub-optimal policy regime on a topic of limited importance without collapsing.
If Hitler had not done anything, i.e. implemented the so-called null policy, nothing bad would have happened. Feel free to substitute with any other dictator if you want to avoid Godwin's law.
