Reducing advertising or making the sale of higher-power lasers illegal won't help, because there's a very common source of high-power lasers: CD and DVD players.
Bollocks. Sorry for the swearword, but I cannot stand inflammatory statements like that. CD and DVD lasers are not high power. Not even close.
Go back and read my posting on the maths of eye damage at altitude. You can overdrive a DVD-R laser to about 20mW, which is nasty if you a a few feet away, but cannot cause damage if you are a few tens of feet away, let alone a few thousand.
The primary reason for the warnings on CD and DVD players is that the lasers are infrared, so you don't have the blink reflex to protect your eyes. Perversely Blu-Ray lasers are safer, as they are visible, and it's really hard to stare into the beam for length of time required for permanent damage.
