The aviation industry does have some clout, but whether they have clout enough to see to it that no American can legally possess high-powered handheld lasers is a different story.
Of course it does and will.
Unless you can come up with a genuine argument for why they should not be banned, eventually they will be.
Unlike gun ownership, there is no huge, powerful lobby (NRA) fighting to preserve the right to own a 2W laser.
There is no counter-argument for why we should be allowed to have them.
There is nothing in the Constitution preserving our rights (and any 'rights' remaining can still be surrounded in red tape and control to make it pretty meaningless anyway - see Gun Control in Kalifornia)
I give it 12 months before even owning anything > 5mW will be a felony.
