So, you’re really interested in this question: what is the best decision algorithm? And then you’re interested, in a subsidiary way, in what you ought to do. You think the “action” sense is silly, since you can’t run one algorithm and make some other choice.
Your answer to my objection involving the parody argument is that you ought to do something else (not go with loss aversion) because there is some better decision algorithm (that you could, in some sense of “could”, use?) that tells you to do something else.
What do you do with cases where it is impossible for you to run a different algorithm? You can’t exactly use your algorithm to switch to some other algorithm, unless your original algorithm told you to do that all along, so these cases won’t be that rare. How do you avoid the result that you should just always use whatever algorithm you started with? However you answer this objection, why can’t two-boxers who care about the “action sense” of ought answer your objection analogously?
