Because mushrooms are NOT "super high in protein".
A comparable serving of beef has about 12x the amount of protein as mushrooms.

We should measure the protein density at a meaningful state for consumption.
While you can eat some mushrooms fresh and dry, their water density when fried is somewhere in the middle. Closer to dry when processed.
How many oz of mushrooms would one have to eat to get the same amount of protein?
Edit: legumes are more practical, green peas give you 2g/oz and peanuts can be 7g/oz shelled according to google, (though they are different proteins than the beef). Mushrooms are good for texture and some like shitaki can give the umami taste, but they aren’t a nutritional meat substitute on their own.
