Does the egg yolk then have enough biotin to counteract the egg whites' biotin destructive tendencies?
It likely varies depending on whether the egg is fertilized and the condition of the person's gut and who knows what else.
If so, then it sounds like you gain glutathione by eating the white alone and you gain biotin eating the yolk alone (probably other things too).
Presumably, healthy individuals who are not too negatively impacted by the avidin would gain both by eating both. This makes evolutionary sense. If humans have been eating raw eggs in various stages of fertilization and embryonic development for millennia and benefiting, and if baby birds benefit by eating the raw egg whites they are born into, which they seem to, then it wouldn't make sense for healthy humans to be damaged by eating whole raw eggs in reasonable quantities. This brings to mind Tom Naughton's simple principle: "Let's start with one simple idea: Mother Nature isn't stupid. She didn't make human beings the only species that prefers foods that will kill us."
Some folks talk about separating the yolks out being natural, but if you've seen wild eggs you know that many of them are quite tiny. I find it hard to believe that our primate pre-human, proto-human and early human ancestors would have spent time separating the yolks from the whites of wee eggs, especially before the invention of wooden bowls and cups, and I've never witnessed that with any egg of any size in any video or write-up of hunter-gatherer peoples I've seen. If it were standard practice, then surely we'd have seen at least one example by now.
On the contrary, I have seen old-time rural American and Chinese folk portrayed in movies poking a hole in an egg and sucking out the entire raw contents, which is what Aajonus does, interestingly. When you do this with a large egg, like an ostrich egg, you can then use it as canteen, which the Bushmen in South Africa traditionally did, and some still do:

I started again, they started laying again - even though they are old - at the same rate they always did. I had tried feeding them raw whole grass-fed cow meat/organs and that didn't do the trick. The whey was different than the meat for them. Makes me wonder.
Sure, but then again, how does Joel Salatin of Polyface farms get his chickens to lay their world-famously-good eggs and how do wild birds lay eggs without benefit of whey dairy products?
