Apparently eggs have already been done, as has milk that can be turned into cheese

Although it's a different process

Rather than grow them by duplicating existing cells, instead you GMO brewer's yeast to produce the proteins you want, similar to how we make insulin now, and then add the few things you can't get the yeast to provide (which with sufficient tinkering, is basically just the shell, and even that can be substituted with plastic containers)

Yeah, sure, lobsters (which are also arthropods) only get eaten because people don't have anything else.

At first I thought you were being completely serious, but then I realized that you were being sarcastic after you told me, good thing you did! Anyway, lobsters were eaten because there was nothing else. Making them into a luxury dish is a modern affectation. That's not an actual counterargument to the real point here, but it needed to be said.

Agreed. But you have not presented any reason for putting "eating insects" in the same category as "shivering in the cold" and "being murdered for your shiny rocks". Some social constructs are useful, but they're not useful by virtue of being social constructs.

My reason is the only reason that actually exists when it comes to the value of social constructs: consensus. Most people find eating vermin to be disgusting for some reason, and they avoid doing so if it doesn't increase their likelihood of starving to death. Which is why you find this aversion to be less prevalent in cultures where famine and starvation exist right now and/or in living memory—and thanks to colonialism, there are a lot of deadly famines in living memory in the third world. I agree that social constructs don't have any intrinsic value, but what difference does it make? Social constructs have the value people place on them, and that value can be imported from other places. Eating bugs is, to most people, disgusting. Like all value statements, this should be understood within its context as being a statement of arbitrary value that is supported by the consensus of a large plurality of people (though this one has majority support). Asking for quantification of it like "why is this a right thing to believe?" is just asking "why do we value what we value instead of valuing something else?", to which the only actual answer that matters is "because it had to be something, and we got this". But as I said, values get imported from elsewhere, like trauma or instinct, such as how European culture developed certain values around hygiene after and in response to the plagues. In my opinion it's reasonable to assume that human beings are instinctively averse to writhing masses of disgusting vermin that are usually found in places like fetid bogs and putrid rotting corpses, and that we are far less averse to things that resemble our ancestral natural prey, like deer and geese.

Also, the idea of the comic as I interpreted it is that the upper class thinks pandering will trick poor people into enjoying eating bugs while they themselves continue to eat meat, which has a meta-point to it told through subtext, like all jokes do: that capitalists value having what other people don't have, that they think the "poors" can be tricked out of it like simpletons, and that they think humiliating the poor and exploiting them in their humiliation is a virtue as long as it's profitable. I would have explained this to the other guy arguing with me, but he gallantly resists being reasoned with and seems much happier nailing himself to the cross.
