Frankly, no. Buildings are burning with people dying inside right now. The situation is an emergency, even if all we've ever managed is ten millennia of triage. That is the default, that is the background. Weigh the risks, sure, but don't act like choosing to do nothing is without cost. We should study asbestos just as much as we need to, as best as we can tell, and no more. In the meantime we need to fireproof all buildings with asbestos.
We did weigh the risks. We did study asbestos. And we as a society made an informed decision that the risk of asbestos outweighed the risk of buildings catching on fire.
I don't understand the point you were trying to make here. Why shouldn't we invest effort to research a technology that might mitigate the 2nd leading cause of death in the developed world?
Edit: /s (If that wasn't obvious.)
