It just feels like the writer is being lazy. We have to perfectly established methods through which the Ants could have obtained Nen, but because neither one is convenient for the story, it feels like he just ass-pulled a new one.

And I feel it´s fine, because it´s really just what I´ve been speculating about. The chimera ants are natural nen-users, they just need a catalyst of sorts to change it from a passive to an active ability.
