And just so we're clear - I don't intend that in a "boo meat eating, let me compare it to violating a sacred value to make it seem dirty" way, I totally support the general idea of trying to calculate the ethical costs of things in dollar amounts.

I mean it in a "there is absolutely no way serving factory farmed human flesh would be that ethically clean in a world where we did that sort of thing and if it is we have a lot of practical stuff to re-think, so your analysis must necessarily be fundamentally flawed and off by several orders of magnitude but I do want a real answer so don't stop trying to do what you're doing" way - assuming I understand correctly. I have seen various attempts at doing this but nothing particularly convincing.

(You did give me the idea to use human flesh tax as a sanity check for these sorts of things though, so thank you!.)
