Site owner can, bureaucrats can't (as far as I can avoid it).
In hang gliding we frequently fly from public lands. In those cases the bureucrats are the ones that require we have insurance and ratings through USHGA. We don't have a "license" in the sense of a driver's license. Our rating/insurance is not a legal requirement. It is however a requirement for flying from these sites and keeping them open. I don't think we could get a ticket or get arrested for flying these sites without the proper rating. However, if we fail to regulate ourselves (i.e. make sure our fellow pilots have the ratings and follow the rules), the site would be shut down (which happens too often in any case).
In many places around the world the beaches are public, and should be kept that way.
I agree. However, the government has the job of regulating the use of the beach to insure no group unfairly precludes the rights of others. They clearly can, and do, shut down beaches to kiting in many places. This hypothetical organization is intended as a way to convince them not to.
e.g. look a the behaviour of the drivers, ......
we have a license. Is it a certificate for good driving behaviour? Look at the statistics.
Too many drivers, too few cops (don't get me wrong, I personally don't care for cops). The object is to police ourself so we don't end up with kite-cops.
Who is the qualified inspector that checks after your sticker?
Every "rated" rider that doesn't want to lose the site. A current sticker would have to be displayed on your helmet, kitepants, thong... If someone tried to ride a "regulated" site without one you don't launch him, and you don't let him launch. Hang gliding in the U.S. doesn't require a license, but I dare you to try and launch at a requlated site without a current sticker.
What about windsurfing ?
The pig-stickers are harmless - aren't they?
