I don't think something like this should be made law. As PADI says, ultimately it's the certified diver's responsibility for her/his own safety. As a soon-to-be-certified DM, I don't really mind taking out new divers, ones with less than 20. I still dive for self/fun, but I use those other dives to practice my own skills, to help others, as others helped me when I was at that point. To echo others, some OW people are better than others more advanced. One of my friends has no more than 20 OW dives, but his skills are superb. Night, deep...no problem. I don't really feel comfortable with the term newbie. I mean, we all like to show how good we are, or how many dives we've done, but really...There's always room for improvement, whether you've just finished OW or have c-cards up the yin-yang. I'm always learning some new trick, some technique that makes me a better/safer diver. I've done 115 dives to date, but still consider myself a novice. There's so much more to learn, that signatures in a logbook don't provide. So, to conclude, I think PADI's system is fine, and there is no need for government interference. By divers acting more responsibly, we can perhaps avoid governments having anything to justify their actions with.
