I am not sure that we disagree on the above. Except, when you single out
fancu as being the only gismu that contains a name, what about "cmene"?
You're right: "f(x)" and "x + 2" are related by cmene, and probably sinxa,
tcita, and smuni.

In ro velvecnu, the nalsku gadri is lo, which can refer to multiple
referents. If I say "every price", how many do you think I am referring
to? Probably, more than one.
In jei mi tervecnu, it's true that the one value used in that range is 1.
But the value of jei spans [0, 1], so in general, that is a real quantity.
