Lasers were not banned and are more heavily used now than ever before. Only blinding lasers were banned by treaty, and even with those China is semi-openly defying the ban.
It’s clear what they where referring to, as the argument was a type of drone being banned not all drones. Saying they “banned lasers” is correct even if they only banned a subset of lasers.
I am genuinely curious if you have a deeper argument. As small anti personnel drones seem suspiciously close to cluster munitions, but might be acceptable.
It was not even remotely clear what they were referring to. There are many different types of lasers.
Considering that the US, Russia, India, and China haven't even signed the Convention on Cluster Munitions there's clearly no political appetite for such bans among countries with large militaries. And such a ban would be unenforceable anyway because small drones are dual use technologies which don't require specialized manufacturing.
