Mandating insurance perverts incentives. Insurance wouldn't necessarily pay out the claim, putting the drone owner in a position of the liability (s)he is in now. Also, this does nothing to change incentives for the electrical grid, which should not be nearly as brittle as it is. That said, this is probably the simplest single solution to address what happened -- assuming anything should be done.
