Let me reassure you that there’s more than enough protein available in plant-based foods. For example, here’s how much grams of protein there is in 100 gram of meat
That is misleading because most foods are mostly water, included the (cooked) meats you list, but the first 4 of the plant foods you list have had their water artificially removed: soy protein isolate;
egg white, dried;
spirulina algae, dried;
baker’s yeast.
Moreover, the human gut digests and absorbs more of animal protein than of plant protein. Part of the reason for this is the plant protein includes more fragments that are impervious to digestive enzymes in the human gut and more fragments (e.g., lectins) that interfere with human physiology.
Moreover, there are many people who can and do eat 1 or even 2 lb of cooked meat every day without obvious short-term consequences whereas most people who would try to eat 1 lb of spirulina (dry weight) or baker’s yeast (dry weight) in a day would probably get acute distress of the gut before the end of the day even if the spirulina or yeast was mixed with plenty of other food containing plenty of water, fiber, etc. Or at least that would be my guess (having eaten small amounts of both things): has anyone made the experiment?
I’ve eaten 150+ grams of raw nutritional yeast in a day without much issues. I’d worry more about getting excessive amounts of certain vitamins. I agree though, this is not a feasible thing to do for most people. Also it tastes terrible so I would not recommend.
