I made a video about a lot of these issues once, but really quick, the argument basically goes like this --
If we always call, villain can exploit us by not bluffing and if we always fold, villain can exploit us by never bluffing, so to keep him from exploiting us, we need to call just enough so that his EV of bluffing and not bluffing with air are equal.
So then we assume he has some air hands that always lose the pot if they don't bluff and also lose if they bluff and get called, and then we call enough to keep these indiff to bluffing.
First of all, the original indifference argument can break down for a lot of distributions (eg what if villain doesnt even hold any air or not much). Second those ideas about the EVs of bluffing and not bluffing are pretty much always wrong. ATC have like 20perc chance to pair up if they check back and get a couple free cards, bluffs and esp semibluffs can still win a lot if they bluff and get called, etc. And it turns out that these things can have a v big effect on the estimated gto strats. So the naive estimate found by calling to make complete air indiff is usually completely wrong.
