I’m not Vegan, so I can’t speak for them, but here’s my understanding
if you live in an urban environment, it’s basically impossible to get what you’re referring to. Maybe if you were willing to have it shipped to you at great cost and not insignificant effort, but the only thing available at stores in the US is the BS marketed “free range” stuff. And even if you find a place that claims to be the real deal, how do you verify? Basically, it’s easier for most people to just go Vegan then to seriously vet every source of animal products
Additionally, many vegans believe it to be a genuinely healthier diet than an omnivore diet. And please don’t respond with " we evolved to be meat eaters" or something like that, because we didn’t “evolve” to do practically any of the things modern life entails, including a lot of what we eat. Beyond that one BS counterargument though, I make no claims as to whether they’re right. Anecdotally, my sister in law suffered from IBS her whole life until she went Vegan, when the problem went away entirely. So it certainly has benefit for some people
Finally, for a lot of vegans it’s an issue of consent - some might say that you shouldn’t eat those eggs in your example for the simple reason that they don’t belong to you, and you can’t morally take them, because theres no way to ask consent, and so you shouldn’t. Again, you don’t have to agree with the outlook, but that’s the way several vegans have explained it to me.
If any actual vegans come along and think I’m misrepresenting something, feel free to correct it
Ultimately this is the core problem as I see it - a hierarchical society will always be militarily stronger, practically by definition - and if history has taught us anything, it’s that weak neighbors get eaten by their stronger neighbors.
Additionally I think most of these idealized community structures are overly optimistic about the likelihood of a charismatic leader coming along and getting people to follow them, and then not letting them withdraw that power. Anarchists talk about hierarchies without formal power structures, but what is actually stopping someone whose already effectively in charge from turning that power into something more permanent, especially if they’ve convinced the populace that they want that?
Its happened an endless amount of times all throughout history, and I really don’t see why it wouldn’t here. Ultimately it just seems like a fragile system that relies mostly on every single individual being perfectly rational and immune to the draw of populist leaders. Aka - completely unlike actual humans
