I’d urge you to consider what “yield” is and means and how “yield” plays out over the whole length of the industrialized food chain.
The classic example from a producer’s perspective is that commodity level production has to be sorted and doesn’t get equal value for everything produced. So you may only get top dollar for 25-50% of what you grew and far less - possibly even zero - for the rest. Incredibly, it really is sometimes cost-effective to let the produce rot in the field if prices don’t support a profit.
Then farther down the chain you have increasing losses and waste. By some estimates that’s as much as nearly 40% of all food produced. See also here.
These factors only very rarely are brought up in these discussions in part because folks have very narrow conceptions of what “yield” means.

There is no alternative. None.
