Yeah. For being a little strange I find the shrimp welfare stuff pretty unobjectionable. Like, he vastly overstates the magnitude of good done by those stunners because he does appear to be a shut-up-and-multiply bro, but I'm comfortable with the general notion that we should be nicer to shrimp and other animals we eat, even the ones that don't make good PETA glamour shots.
Ed: oh sweet merciful Jesus the Epstein take. Nope. I'm actually investigating whether we should torture shrimp even harder just to make sure since their most ardent defender is like this.
It's also fascinating because I thought the OP was pretty clear that there's a difference between decision theory and "desirable dispositions" which I interpret as covering the kind of counterfactual preferences indicated here. Actually there's an even more fundamental issue with this as a decision theory problem which is that it misidentifies who is actually making a decision. Changing the applicant's decision theory (while leaving their preference for thievery intact) doesn't matter to the person actually deciding here.
Don't get me wrong, it's also a wildly racist example to put forward, it's just also a bad example and where there is an argument it's addressed in the OP.
