Lasers are used in so much technology, I don't see how they can outright ban them, what about owning a media projector, or a party projector, or even a pico projector? A person could end up with a defective pico projector that throws beams??
What is the exact letter of the law....can you find a loophole?
The airplane pointer idiots won't look, and once they all get picked off things will quiet down.
You either have to take it head on and fight it or lay low and wait for the winds of change to blow, but it's hard to get anything back from government.
What about professional laser show equipment, can you get a license for that?
What will probably happen here in the US is it will all get expensive, only those who can pay the annual license fees and insurance will be permitted, but we haven't crossed that bridge just yet, but I see it through the fog, hopefully we don't go that route.
First discover the exact letter of your laws, then look for loopholes and exemptions, your hobby may get expensive.

A person may want to keep thier lasers indoors for a while, maybe even build them into a clock radio or old style camcorder until the outrage dies down, your political system is different so I'm not sure how to tell you to fight, you might be better off to try and get a waiver, but in your case you may want to tread lightly for now.
I would look into professional light show equipment and discover what a presenter in your region is required to do to be legal, see if there are different levels of license, you may want to give it time, I would want to fight for freedom, but our systems of government are different...none are getting any better, except for China, their people are slowly gaining freedom after getting a taste of capitalism and they like it.
