That dilemma seems very specific to Canadian law (or any situation where such a law exists). The thing I asked was whether it makes sense to remove the concept of property and markets entirely from meteorites. Sayings yes it's property but adding a minor exception wouldn't eliminate the incentives entirely... but it could severely reduce the incentives to find them and therefore the net gain scientists (and the public) get from making it open to the private hunters. Those details matter a lot in that context, do they have to turn it over indefinitely for 'research'? Do researchers have to compensate the finder if they take it for an extended period of time? etc. That's basically a whole different conversation that's predicated on the core question I proposed but it's a different question.
