If any of the planet saving meat substitute promises are true, such a fake meat patty would cost a tenth of the beef equivalent and it would dominate the market.
That would only be true if the cost of the patty was only thing that impacted the price to the consumer, but everything else like transporting the thing to a store, paying the store staff to sell it, paying for marketing, branding, etc, paying taxes on it, are essentially the same regardless of whether the patty is made of cows or plants.
