No, this is more about deleting a tiny discomfort - say, the fact that I know that all of it is an illusion; I attach a big value to my memory and especially disagree with sweeping changes to it, but I'll rely on the pill and thereby the AI to make the decision what shouldn't be deleted because doing so would interfere with the fulfillment of my terminal values and what can be deleted because it brings negative utility that isn't necessary.

Intellectually, I wouldn't care whether I'm the only drugged brain in a world where everyone is flying real spaceships. I probably can't fully deal with the intuition telling me I'm drugged though. It's not highly important - just a passing discomfort when I think about the particular topic (passing and tiny, unless there are starving children). Whether its worth keeping around so I can feel in control and totally not drugged and imprisoned...I guess that's reliant on the circumstances.
