I don't know why some people want vegetarian food to taste like meat. I enjoy eating meat, but the best vegetarian foods that I had did not taste like meat at all, and it is how it should be. It's like with sugar, if I want to avoid consuming it, I don't replace it with sweetener, I just don't put the sugar in and enjoy the untainted taste of the other ingredients.
It's not trying to be this "best vegetarian food that you had that did not taste like meat at all, how it should be". It shouldn't be like anything. Both food options can co-exist. You're completely misinterpreting the niche it's filling. If I want tasty food, I'll eat something that's veg-based and tasty, not mock-meat. 90% of my diet is curries, chillies, stews or stir-fry's and I'm more than satisfied - but if I crave something that I can't/won't eat, you bet your arse I'm going to go for the worse tasting, greasy, salty, crave fulfilling option, be it an Impossible burger or some crappy cardboard tasting mock-meat.
