primitive hunter gathers in the hundreds of thousands without requiring a bug diet
That is not true. We aren't as capable of cataloguing the diets of prehistoric cultures for obvious reasons, but one such culture that did survive to the modern era includes moth caterpillars among its more famous examples of "bush tucker." There is archaeological evidence of insects being eaten in other hunter-gatherer cultures, too.
Which isn't to say that we should be eating bugs now, of course. Active cultivation of food supplies produces far higher food density than just browsing what is naturally available and eating anything you can find. And if someone is worried about the inefficiency of beef production, they can always eat chicken instead of skipping all the way to grasshoppers.
