well the thing is it isn,t for you to decide, or even care, i don't have to have a need or legitimate reason to have something i want. it is called freedom.
do you have legitimate reason to post on any board? have a computer? tv? not according to your logic, can you live without it? yes. lets ban it too. you don't need it.
I believe that when living in a "society", what's so called "freedom" is never absolutely free (hence the laws and justice?).
Therefore, just as much as some people want their human rights to do whatever they want, the others want their rights to live peace, to be protected.
It's true that it's not for me to decide but "coincidentally", that "freedom" allows me to state my opinions just like you voiced yours.
As a matter of fact, I do care because I don't want myself/ my family/friends/pets(/flashlights?) to be in a situation where the aircraft carrying them just "happens" to have problem with landing (or any other immediate dangers) as some idiots are targeting it with their lasers.
And actually you missed my earlier point, things like forks/spoons/pcs/internet/.. are appropriate needs because they can increase the quality of people's lives in some ways (well, to more than just "some" people anyway), while a high-powered laser is only good for a small number of individuals.
Perhaps going through an engineering degree has significantly affected my points of view but my (Yes, "MY") rule #1 is: Safety always comes first.
