Yes. Isn’t it true that people who go vegan at one point in their life revert back to eating animal products? I remember this was the case based on data discussed in 2014 or so, when I last looked into it. Is it any different now? Those findings would strongly suggests that veganism isn’t cost-free. Since the way you ask makes me think you believe the costs to be low, consider the possibility that you’re committing the typical mind fallacy. (Similar to how a naturally skinny person might say “I don’t understand obese people; isn’t it easy to eat healthy.” Well, no, most Americans are overweight and probably not thrilled about it, so if they could change it at low cost, they would. So, for some people, it’ isn’t easy to stay skinny.)
Maybe we disagree on what to count as “low costs.” If their lives depended on it, I’d say almost everyone would be capable of going vegan. However, many people prefer prison to suicide, but that doesn’t mean it’s “low cost” to go to prison. Maybe you’re thinking the cost of going vegan is low compared to the suffering at stake for animals. And I basically agree with that – the suffering is horrible and our culinary pleasures or potential health benefits appear trivial by comparison. However, this applies only if we think about it as a direct comparison in an “all else equal” situation. If you compare the animal suffering you can reduce via personal veganism vs. the good you can do from focusing your daily work on having the biggest positive impact, it’s often the suffering from your food consumption that pales in comparison (though it may depend on a person’s situation). People have made estimates of this (e.g., here)! Again, the previous point relates to the same disagreement we discussed in the comment thread above. If someone does important altruistic work, everything that increases their productivity or priorization by 1% is vastly more important than going vegan. You might say, “Okay, but why not go vegan in addition to those things?” Sure, that would be the ideal, in theory. But in practice, there are dozens of things that a person isn’t currently doing that could improve their productivity or prioritization by 1%, and those 1%-improvements would be a bigger deal in terms of reducing suffering (or doing good in other ways). So, unless one first implements all those other things, it doesn’t make sense, on consequentialist morality, to prioritize personal veganism.
I admit I’m getting confused. I think you’ve moved into arguing that going vegan has low relative value or may not even make sense for a maximising consequentialist. In my thought experiment I was trying to be agnostic on these points and simply draw a parallel between eating mentally-challenged humans and animals.
If you want to say that going vegan doesn’t make consequentialist sense for ‘reason X’ that is fine. I’m just saying that you then also have to say “if I imagine myself in a world where it is mentally-challenged humans instead of animals, I would not stop eating the humans for the same reason X”. If you can say and mean this sentence (I expect many people can) then this thought experiment should not have an affect on your choices. To clarify I don’t really judge such people—they would be acting in a morally-consistent way which I think is one of the most important things in ethics.

I agree with that. Some of your earlier comments seemed like they were setting up a slightly different argument.
Someone can have the following position: (1) They would continue to eat humans in the thought experiment world where one’s psychological dispositions treat it as not a big deal (e.g., because it’s normalized in that world and has become a habit) (2) They wouldn’t eat humans in the thought experiment world if they retained their psychological dispositions / reactive attitudes from the actual world – in that case, they’d finds the scenario abhorrent (3) When they think about (1) and (2), they don’t feel compelled to modify their dispositions / reactive attitudes toward not eating non-human animals (because of opportunity costs and because consequentialism doesn’t have the concept of “appropriate reactions” – or, at least, the consequentialist concept for “appropriate reactions” is more nuanced)
I think you were arguing against (3) at one point, while I and other commenters were arguing in favor of (3).
I’m not sure what the cost of changing one’s reactive attitude is. Do you mean the cost of going vegan? If so what do you see as the main costs?
