There is a huge thread basically refuting the parent's "nobody wants this" claim.

The fact that the Beyond Burger sells in mainstream grocery stores tells you all that you need to know: it's popular (enough). There are muliple products in this niche in my not-very-large grocery store.

Grocery stores don't stock products that don't sell. No matter how you personally think it doesn't have a niche.
