Lets put it this way, do you want to be put at risk when your plane is landing because some idiot bought a laser on eBay and is trying it out on the cockpit? It is not temporary safety, it is because there is no reason you should have a laser pointer which can easily blind people, the damage it can do it a lot worse then the benefits of it. There is a reason you are not allowed to carry guns on airplanes, not because of temporary security, but because there is absolutely no use at all for them besides things that would be harmful to other people.
I think it is good that it is very difficult to get guns, it makes it so there are less of them out there. In the US, you can go get a gun at a gun show and there is no record of it, that is a serious problem, it should be more difficult to get a gun then it currently is.
