What I am trying to point out is the almost total impossibility of a organization revoking cards for incompetence on so many hundreds of thousands of divers around the world. That's why I kept asking the questions about how it could be done. I would certainly rather not have a governmental agency stepping in with more regulations, as is happening in several locations, but I am still waiting to see a feasible way to do it. If you can't show how it can be done feasibly, then how can you say it will be a better alternative?
I'm not necessarily conceding it couldn't be done feasibly. I think a system of accident-based reporting and consequent investigation that could result in action against a certificate *might* work, and might be a limited enough internal regulation to forestall external regulation and not screw up diving in general.
Or there might be a better way, if more heads got together. But if we like the system as-is, then okay, heads won't get together. I just think the as-is will not produce a very robust "we are policing ourselves" defense against possible government encroachment.
