For instance, what you say about 'NEVER supplement[ing] with iron' is quite wrong. Iron deficiency anemia is quite common, especially for young women; and it is routinely treated by iron supplementation [1], even over-the-counter: if anything, iron's bioavailability in adults is very low, and it is difficult to exceed safe levels (although it's the opposite for children) [2].
Also Vitamin D2 is not useless at all. Even though some recent studies have shown some limited evidence that D3 is stronger and longer-acting; decades of clinical practice have shown the safety and efficacy of high-dose D2 in treating severe vitamin D deficiency [3]. It's disingenuous to say otherwise.
And... what you say about Vitamin K1 vs K2 is also far from well-established. Putting aside the fact that actual clinical vitamin K deficiency is extremely rare in the first place, K1 is the most commonly used form for a reason: even though there has been some recent work indicating possible differences in bioavailability and function on the part of K2; current knowledge is still very limited, and there is not enough evidence to displace K1 as the main formulation approved for dietary supplements [1,2].
I could go on and on with other inaccuracies in what you said, but you get the idea.
Also be careful with overdoing that liver with onions habit. Even though animal river is very rich in iron and copper (which likely explains part of how you feel after eating it); it also happens to contain high amounts of vitamin A in retinoid (retinol) form, which as you correctly point out should be taken in moderation due to their much higher bioavailability vis a vis carotenoids, thus increasing its potential toxicity [7].
