I don't understand vegans at all

no it doesn't, it needs to be digested by ruminants first, and it's lacking micro nutrients and sufficient levels of protein.

eating a truckload of plans for the equivalent of 1 small piece of meat isn't efficient either

yes it does

To produce 1 kg of protein from kidney beans required approximately eighteen times less land, ten times less water, nine times less fuel, twelve times less fertilizer and ten times less pesticide in comparison to producing 1 kg of protein from beef. Compared with producing 1 kg of protein from chicken and eggs, beef generated five to six times more waste (manure) to produce 1 kg of protein.

to produce 1 kg of animal protein, 3 to 10 kg of plant protein is required, depending on the particular animal species and circumstances

vegan diet is infinite times more cost efficient and eco-friendly 

I eat meat too because it's hard to otherwise meet my macros 

Like you said, you need to eat a much larger volume of food

But at least I'm not lying to myself
