I think the point is that if it's that expensive, some other alternative is likely to win. There are other meat substitutes, which are already having some success.
Expensive technologies win a lot of market share only if no other alternative can work, and even then their use will be minimized.
It's actually smarter than the slavery statement. Slavery wasn't just cruel and sick; it was also economic insanity, the biggest waste of potential in at least America's history. People, educated, free and motivated to innovate, are our greatest asset.
(Innovations do break through, of course, even from people denied those things. But even the richest elites would be better of if nobody had to overcome those barriers.)
Such drama. We've evolved over millions of years brains so large that we now think that eating food is murder. Our "monkey" ancestors are laughing at us.
