I think your comment acknowledges that we're not running this experiment. These "fake meat" products are still way more expensive than actual meat. If fake meat actually drops substantially below the cost of meat, we can see what happens, but as you suggest there's really no sign they can compete on price yet.

I do think that if the target market for Beyond really was meat eaters, they've been deluding themselves. Maybe they can shave off a few meat eaters due to the ethical issues, but how many? Ultimately, I have to assume the only way to win many over is on cost, which would have to be a high volume low margin business (if it's even possible to get the prices that low).
