I wouldn't overthink it too much. Normally it'd be rude so baldly to note how wildly off base you are about so much of how ant societies work, but in this case it's worth mentioning because what does that say about your chances of accurately apprehending the parts of this analysis that aren't tangible? You almost certainly do not need to fear living ten million lives as an ant before reincarnating as a human again.

(If you are going to reincarnate as a hymenopteran, go for Polistes, that's my advice. Social, but on a smaller scale and in a looser style than Vespula and hornets, and with size and brains enough to manage a degree of personality that ants in my experience don't seem to. Also, you'll be able to fly! That seems like a considerable benefit entirely in its own right.)
