As per a recent comment this thread is meant to voice contrarian opinions, that is anything this community tends not to agree with. Thus I ask you to post your contrarian views and upvote anything you do not agree with based on personal beliefs. Spam and trolling still needs to be downvoted.
And 3 utilons. I see no cost there.
But presumably you don't get utility from switching as such, you get utility from having A, B, or C, so if you complete a cycle for free (without me charging you), you have exactly the same utility as when you started, and if I charge you, then when you're back to A, you have lower utility.
