Safety and Selfishness

Just as an offshoot of the thread where one member thinks wearing a leash is 'not cool', and following on from a summer of watching idiotic antics in the water, I thought I'd ask whether it's just me, or does anyone else get annoyed at the sheer ignorance of many people who try surfing.
From the numerous threads on the subject, it appears many are totally confused by many aspects of surfing etiquette (but at least if they're on here they generally get put straight) - so should it be the requirement of all surfers to have a 'safety test' and carry insurance?? (I know some places where insurance is a must - as is the wearing of leashes)
Should everyone have to have a licence - gained after a basic lesson on safety, water craft and etiquette - or should hire shops shoulder some responsibility before hiring out boards???
Just curious as to anyone else's thoughts on this ............
