Animal rights libertarianism: it can be realistically be put into practice if human rights libertarianism can

I was going to write something about what would be involved in "uncompromising respect for rights" both in the case where your circle of rights-holders is all post-natal conscious humans and in the case where it's all post-natal conscious members of the animal kingdom, and then I was just thinking about foreseeably causing death to others through air pollution... like have libertarian writers already written on that topic, apart from Murray Rothbard? Like, Robert Nozick says it should basically be a tort handled by the court system, and anarcho-capitalists could say the same thing I guess, and that's even in the case where the harm is accidental death...

Well, all right, why can't vegan libertarians handle the problem of collateral deaths from plant-based agriculture in the same way? They're accidental deaths caused by the food production process, someone gets authorized to collect the cost of the externalities you accidentally impose on the wild animals (they can be funded by charitable donations if you want to be an anarcho-capitalist), so that cost is factored into the price of the product and then the market forces drive the entrepeneurs to come up with harm-free methods of food production. However, it's still obviously completely out to have non-human animals as items of property that get used for food. So a vegan libertarian can consistently say that's the ideal state of society, and then with a clear conscience they can buy plant-based food from the supermarket and offset the harm accidentally caused from the production process with charitable donations aimed at reducing animal suffering.
Isn't this the "animal rights libertarian" solution to the issue?
