If im not mistaken it was weston price who did not find a single people who ate a diet completely devoid of animal foods which was doing well
That is because he didnt find any culture traditionally following a vegan diet. The only people he found not eating any meat or open range dairy were basing their diets on white sugar and unfortified white flour.

many of the peoples he studied did eat grains, but the point stands none of them were basing their caloric needs around them, the irish had their oats and the swedes there rye, but each had access to extremely fresh high quality animal food in the form of fish and cheese respectively.
Fish and cheese were not the basis of their diets. They were a substantial and central component, yes, but the majority of their calories came from whole grains.

i would like to see where it was disproven that phytic acid/phytate is not able to be broken down. Im fully aware of the positive qualitys of the said compound some people even supplement it, but in the context of the already nutrient deficient diet many today follow i dont think many want to lose the chance at any more magnesium and calcium than they have to.
Meat and dairy is horribly low in magnesium. To get magnesium you need to eat plants.
This paper shows phytate to be partly broken down in digestion
This one shows that the other things in your meal can increase bioavailability of iron and zinc in grains irrespective of phytates
Here we can see that leavening bread even with just manufactured yeast will break down phytate and free up minerals. Traditional cultures used sourdough, of course, which breaks down more.
Literally tens of thousands of such papers can be found through
google scholar, which is a great search engine.
Hard-science nutrition societies,
like at cambridge university, dont hesitate to class phytates as beneficial components of the diet.

Where does a vegan get their fat soluble vitamins a d k and e in the quantities necessary for good health? Sure theres betacarotene but it cant be converted into retinol in the body in the absence of the bile acids which digest fats so a extremely low fat vegan has very much trouble getting vitamin a in usable form. Sure d can be made from solar energy and k1 is in many greens but the sheer amount of matter which must be consumed to aquire adequate amounts of these compared to whats in meat is far less feasable in long term.
You should be aware that animal products are fortified with vitamins A and D, and often E, because they are such
bad sources of those vitamins. Just read a milk jug. Organ meats can be rich in them, true, most meat eaters dont consume much of those though.
Vitamin D comes from the sun. People at risk for late-winter deficiency like dark skined people in canada and people at risk for late-winter insufficiency like old people in the northern half of the US could sun bathe some dried mushrooms in the summer and store them for the winter or they could use a supplement pill once a week for those couple of months. The liquid pills are absorbed best. Plant foods are the best source of vitamin A. Our bodies can convert pro-vitamin A to vitamin A as needed, thus avoiding overdose toxicity. When the active form is got from meats that safety measure is circumvented and people can overdose. Any green plant is a good source of vitamin A and low fat vegans still do produce bile.
Vitamin K only comes from plants and bacteria. Its where animals are supposed to get it, any in meat is there because the animal ate plants or, more likely, the animal was drugged with pharmaceutical grade mock-vitamin K because the animal was not allowed access to plants. Vitamin K deficiency is never seen in vegetarians.
Vitamin E comes from grains and nuts with a little in leafy vegetables. Unfortified meat is nearly devoid of vitamin E.
I wouldnt say meat should not be in the human diet, in most cases thats an issue of ethics rather than health and ethics is a personal thing, what I am saying is that if you decide to have corned beef and cabbage for dinner
dont forget the cabbage!
and perhaps have some whole grain sourdough bread as well, so you get some minerals and fiber.
