NO!
It would never work far to many air guns out there already. Why do you feel the need to license everything? Before ya know it you'll need a license to ******* breath. Its madness! And I suppose with the license a fee would be introduced, another tax on the already law abiding citizen.
I tell ya whats a better idea. License prospective parents. Make them take a test before they have children to see if they are intelligent enough to bring them up. Now that would stop 99% of all the imbicile children getting hold of airguns and causing us decent law abiding airgunners problems
