Great to read this. I’m sure this will go over quite a few heads as a lot of Anarcho-Capitalists have sentiments against veganism, and vegans have sentiments against capitalism. While, as you say, their actions couldn’t be clearer without them realising it.

I don’t see many people who are at the intersection of both arguments. Being both voluntaryist (or a libertarian variant) and vegan seems to be a rare flavor.

I like how you described the part that leveling the sentient being, who experiences pain, up to be included into the NAP doesn’t automatically mean they get the same status and votes/rights as a cognitive, self-aware rational human. It exempts them from being property (at the very least).

I also rarely see animal rights activists talk about something akin to the NAP extending to humans and children in particular. Which is not to say that they don’t care about it I’m sure. Though most of those sentiments are mainly emotionally motivated and the injustice towards innocent animals takes higher priority in those emotional states because of what is seen (we don’t often see child abuse in our daily lives, but we can see videos of slaughterhouses and the meat in a supermarket is proof that innocent beings were killed).

I think both lines of thinking can learn a great deal from each other if they reflect on themselves more, see the kinks in their assumptions and try to define the principles they stand for more clearly and strive to be more consistent with them.
