And what makes Lojban superior to any other language besides noone speaks it
? Why not Klingon, Esperanto, Soresol or even Lingua Ignota?
I don't want to bash Lojban. It is very interesting by itself, but i don't see a reason what makes it special for our purpose here.
The benefit of Latin is, that a lot of people understand it and it is to some extend associated with old sigils and emblems - in the western World. Elsewhere my point is pointless. Therefore I proposed an iconographic language. But I don't see that Lojban is reasonably common anywhere in the world.
