At both food stores I shop at, there are already freezer sections of fake meat. Mostly (entirely?) based on extremely heavily processed soy. I would imagine this different form of fake meat would sneak into that same section.
I would bet you could sell more "real" fake meat to vegetarians sick of flavored tofu easier than selling "real" fake meat to omnivores used to the real stuff.
Back when I used to eat soy, I occasionally would eat "steaklets" which seem to have disappeared from the market. They were basically soy bean hashbrown "pucks" with meat flavoring. They were strangely good, but by no means could you confuse them with "meat". I would expect it to be much easier to adulterate "real" steaklets with fake "real" meat than to adulterate a genuine steak with fake meat.
First off, many vegetarians don't eat junk food out of the freezer; there are many wholesome and delicious alternatives to "flavored tofu." Second, many celebrate lab meat for its potential reduction of animal exploitation, but that doesn't mean that they will eat it. The preference for it is often lost early on.
It's more of a social courtesy akin to not prosthelytizing or shilling commercial products. HN is not a very good place for those kinds of things, nor is it a good place to tell people they're not emoting correctly in a bid to bully them into caring about factory farming.
This isn't really about factory farms or anything specific. It's a broader issue of people thinking with their gut without calibrating their gut first. If you get chills about things that are irrational to be averse to, and don't get chills about things that make sense to be averse to, then you need to either figure out how to bring your instincts in line with reality, or learn when to ignore your instincts.
Where reality is defined as reality. Aversion to synthetic meat, as a concept, is irrational. There is no reason for it. If you disagree, explain your reason.
You make the claim that aversion to factory farming is rational, but you give no further explanation than to loudly exclaim that reality agrees with you, which is a singularly pointless thing to say.
Why should I have to state the obvious? Factory farms are terrible for the environment both in the short-term immediate vicinity, and in the long-term globally. They are massively increasing our exposure to antibiotic resistant strains of bacteria. They expose workers to serious health risks. They treat their animals inhumanely. If you are not troubled by at least a subset of those things, you are either irrational, or your base values are so profoundly opposed to my own that I consider you an obstruction.
