So, do you want to ban wireless presenters or laser rangefinders? Requiring a license for these would be akin to banning them. Except if "holding a presentation" would be enough to get a license. In which case I think the limit would be useless. Maybe limiting them to adults might help. On the other hand, there are plenty of other ways for children to do stupid, permanently harmful things; and exactly the children that shouldn't be let near lasers would probably be able to find some anyway, so... I don't think the licensing idea would work. And shining lasers at aircraft already carries a jail term. And maybe the power limits could be made somewhat (much, actually) stricter.
