All of which begs the question: Why? If you don’t buy the BS about climate change in particular, why would you want fake meat when you can have the real thing
The obvious answer is long duration space flight. There’s simply not enough room to take livestock along even in frozen cut up form. When not if humans go to Mars they will be on vegan diets due to the mass restrictions alone. Once on Mars growing food in hydrophobic greenhouse will still only supply vegan ingredients this would be an ideal way to jazz up the diet.
