The next step though is significantly harder, which is the analysis of "ranking" pleasures
Please don't take this as some kind of ad hominem, because it's not meant that way...
But why?
Why do you want or need to rank pleasures?
I thought the "All pleasure is good" precluded the ranking of pleasure.
Maybe ranking desires for specific pleasures is possible (Epicurus did do that after a fashion with necessary, natural, etc.), but by definition pleasure is good.
I might even amend my post above to say the pleasure of breathing, eating, are both natural and necessary. The desire to eat shrimp instead of bread is natural but not necessary.
