Like, I do think in an ideal world everyone would be vegan and all animals would be free not to be our food...
...Buuuttt I've been eating their products for my entire life and they constitute the vast majority of my favorite foods/drinks and foods/drinks I just like in general, and am thus unwilling to give them up even if I know it would be the better thing to do.
I mean, I probably could if I really, really wanted to, but I just don't want to.
Some do. But they are kind of prohibitively expensive.
Pulled jackfruit can taste exactly the same as pulled pork, but does not have high enough protein content to be a good sub on its own. Properly cooked Beyond/Impossible (I forget which) looks and tastes like meat. I've done both of these as side-by-sides with real meat for mixed crowds and been able to fool people.
Interesting. I haven't tried the highest end substitutes.
They are pricey, but worth it for a special occasion.
The other ones, I agree. Something like field roast is kind of similar to a chicken sausage, but it's best if you think of it as its own thing. Still tasty.
The cheapest "nearly spot on" substitute I've had is the Trader Joe's soy chorizo.
