Meat provides a certain texture and satiety to the appetite that some people crave. Until alt-meat products can replicate that, animals will continue to be killed for their flesh.
It's probably not targeted at vegetarians. They'll want to drive the price down until it's cheaper than keeping livestock, and then all the fast food places will replace their meat with this meat.

In all seriousness, wouldn't it just be cheaper to grow plant proteins?
