Sure the consumer won't consume 10x more, but they're still going to reach for the better products.
And let's say that work is correlated with quality. Company A wants to spend 10x less time working, while Company B works 10x more. Company B therefore has a better product than Company A, so eventually Company A goes away. The consumer still consumed the same amount, but they switched to the better product.

Either the product was 10x better, which I don't think I need, or it wasn't really a 10x increase in productivity.
