So you essentially want to go back to the good old days where the rich and powerful gorged and feasted on the finest foods imaginable while the rest of humanity fed on the scraps. You want the common man to be priced out of high quality meat which is both tasty and nutritious. You want them feeding on some amorphous fungal slop made just for them.
Not the poster: but I want the price of food to represent its true cost and not be artificially cheap (or expensive) because of externalities.
In the United States, we don't have a real market in water; hence, the cost of water in food isn't really represented.
Worse, we "export" a whole lot of water for artificially cheap. Countries with insufficient water to grow crops they would like buy water-intensive crops from the US where water is artifically cheap; hence the massive exports of alfalfa to China. In turn, US aquifiers are ending up depleted and catastrophe looms.
Fixing this, though, will have other effects like perhaps doubling the price of steak. We'll still eat more of it and at a lower cost than we did 75 years ago, but not as much or as cheaply as today. Quality will also probably rise, too, as the measures that produce higher quality beef will be a smaller proportion of the price.
Meat is not scalable. If 8+ billion people want to live on this planet, they will not all be eating steak every night. Sorry if that offends you. If people find an alternative that looks, tastes, and acts like meat but is as or more nutritional and much less ecologically damaging to produce, then great, problem solved.
Secondly, the only reason "the common man" can afford meat in the quantities he can now is because of massive amounts of subsidies and incredibly damaging practices.
So frame your overly-emotional argument however you want, but there are realities you aren't addressing and they don't go away because of your feelings.
Here's a reality you aren't addressing: people don't really want to eat insects. Here's another: about 2 years ago a president was elected in my country partly by promising that the poor would get to eat meat regularly once again.
Make people miserable at your own peril. The simple fact is nobody really wants to be reduced to eating worms and bugs. No one really gives a shit about how "scalable" it is either. Whoever finds a way to provide what people want will have enormous power.
> If people find an alternative that looks, tastes, and acts like meat
Pretty big if you got there. The "alternatives" so far don't really fulfill any of those criteria. They also have the added bonus of offending a person's basic dignity with the knowledge that they're eating insects. There are literal animals out there who receive better treatment.
