People aren't going to care enough unless its significantly cheaper than meat and equally as much effort for the consumer but a lot of vegan alternatives to meat aren't. It should be cheaper for all of the same reasons that it's more environmentally friendly. Plus why full vegan? It's more likely that people will move in small steps vegetarianism is still an option. We lose so much with the all or nothing approach.
Yeah thats a problem I have. I like some plant based meat/dairy alternatives but can't justify paying so much. Meat and dairy should be quite a bit more expensive compared to plant based.
A vegan (or low-meat diet, for that matter) does not equate to substituting meat to processed meat alternatives. Other recipes that do without any fake meat exist.
