It’s not veganism that relies upon capitalism, it’s meat-eating, or at least the intensive meat-eating that we see in developed nations.
Most pre-capitalist societies (barring those that live in extreme climactic conditions) ate a predominantly plant-based diet, with occasional animal products. It is only with the rise of capitalism that came the absolute horrors of the factory-farming industry that has enabled people to eat meat 3x a day, every day.
The meat industry is also destroying the planet while exacerbating food injustices (takes many more resources to produce meat than it does plant-based food). It’s meat eaters who are therefore the privileged ones.
