I think the claim that it’s very costly is just clearly and straightforwardly true. You’re effectively asking me to commit several hours of my time to this post – an order of magnitude more time than I’d usually spend on even a very good EA Forum post. Free time is scarce and precious, and the opportunity cost of spending so much time on this is very high.
I’m asking you to do this iff you yourself feel that you want to do it.
