Yes, there are circumstances where it would provide benefit, but it won't have as much impact in reducing gun violence as a simple registry system would for about the same overhead costs.
Well, I think even if the insurance is subsidised by a lobby group such as the NRA they're still going to be leery of big payouts due to the actions of irresponsible gun owners, so I suspect even their premiums are likely to reflect the risk a particular owner exhibits and in so doing could actually change risky behaviour for the better.
But I also agree that the other measures such as registration of the weapon should also be implemented.
Oh and proper enforcement of existing laws which impact those 2A rights but for some reason seem to be considered acceptable.
