I don’t recall having called people who live on the moon “Lunistas”. I called them Lunarians, after the coinage by James Hogan.
Most writers treat the moon as simply another place to live, without giving consideration to the effects of continuously living in a one-sixth gravity field, and the possible psychological effects of living there.
I would surmise that one of the first things that a serous population of lunar dwellers would do is establish a place that rotates for artificial gravity so that they can prevent bone loss and muscle atrophy, or to recover from those effects.
What they may choose to call themselves I do not know, but I suspect that Lunistas will not be on the table.
“Mechanically inclined—I screw everything up.” Please excuse Lunarian misquote.
