Also I think for most (dare I say ‘well informed’) people it would be an ethical relieve to stop consuming eggs and other animal products.
And yes: there are (nutritional) concerns around eggs; for example concerning salmonella, cholesterol and saturated fats. Although I should mention science is not unanimous regarding all of those subjects.
But science is clear about one thing: bird flu is not to take lightly.
From my perspective, your point can be regarded as a myth.
But even if it wasn’t mostly a myth: I rather spend a little more effort on balanced nutrition than contributing to the immensely violent system that animal agriculture is.
Land use for animal agriculture has shrunk over time in the US. Methane is highest for cows, not that high with chickens. With the right practices (admittedly, they aren't migrating the clocks to fertilize land) this could be carbon-neutral, but notwithstanding, methane does not persist in the atmosphere nearly as long as CO2 does.
Personally I am just choosy about where I purchase my animal products. You can visit some farms yourself. Of course if you're of a certain disposition, you won't want to do that anyway.
I think the bulk of the animal industry and farming industry are despicable and cruel. I think they essentially low-grade poison our food in order to squeeze unnatural levels of production out of goods. Without a doubt, they torture animals in order to increase yield and maximize it to the space. This is grotesque and awful in my opinion.
But there are people who are trying to do it a good way. If you believe that any sort of animal husbandry is evil, then go ahead and lump all the farms in together. But if you aren't that extreme, then there is a huge difference between some of the players.
When I read things like "animal agriculture being devastating for the world including the environment", it rings true, and makes me want to dig further, support this any way I can etc. The conflation with the (IMO hella sus) health arguments makes me question the judgment and intent of the writer, and second-guess my initial agreement.
I would find it easier to sympathize with the main purpose, if it was left to stand on its own. Trust is an important concept in human interactions.
*Reading further posts in this thread, I'm going to double down and add my own frustration: I really want to support this cause and perspective, but I hesitate because I consistently get signals that the people who promote it are arguing in bad faith.
Though I think it's more useful to consider what you could replace it with if you did want to do the optimization.
I've been fiber-maxing and ApoB-minimizing for years and my breakfast lately is usually a large bowl oats + mix-ins, a tofu scramble, or a tempeh dish. According to cronometer, they have similar nutrition and calorie profile of six eggs, except they have fiber and other perks.
The downside is that it took quite a bit of motivated behavioral change to end up with new dietary staples having grown up in our egg-heavy culture.
