My point is that without a license more accidents will occur.

Vendors currently do train their customers and certify them.  

A lot of companies dont send their personel to training lessons because
of the costs. The vendor primarily trains how to _implement_ a BGP
policy on their equipment and not neccessarily how to develop a good
peering and filter policy.

The "youtube ip hijacking" case _may_ be a result of route
redistribution from an internal routing protocol to BGP without any
route filters applied. Every decent BGP engineer knows that this is a
very bad idea.

LIRs don't and
cannot know all the gear out there and configurations from network to
network vary.  

They dont need to. They could/should ensure that people running ASNs
have a good knowledge about how BGP works. Not how to _implement_ a BGP
policy on a vendor device. This truly is up to the vendors and ISPs.

This doesn't stop route leaks, nor would this protect us from
intentional mischief.  

True, but it will help reducing incidents which will have a huge impact
on the live and economy of a lot of people. The "youtube IP hijacking"
was only a minor nuisance in relation to what can happen if other
prefixes are "hijacked" or just leak due to clueless personal.
