It's not about the effectiveness of the repair. It's about the design of run flats.

Run flats have a certified distance that they can be used in a deflated state.

Once you exceed this distance the tire is no longer safe.

There is no way to track the number of miles your car was driven with the run flat deflated.

Sure, you can track it yourself. But are you really gonna risk it? Either way, bmw and the run flat manufacturer are not willing to risk it.
That's why you need insurance. This way, every flat you get a new tire,
