Well, no. In an ideal world yes. But that's not our world. There doesn't have to be some way to reach everyone that has ever purchased a product. For the vast majority of the history of things being sold that has not been the case. It wasn't even in the realm of possibility.

It would be nice. It would save lives and avoid tragedy. It is not required, and failure is an option. We've been failing for a long time already.

If we have to do it, it's a simple matter of finding who has the capability to do so and force them to, as you say. But we don't. Forcing someone to do only because they can is a tricky proposition.
