I don't think your version of Nozick's experience machine actually demonstrates that people prefer other things over happiness. Suppose you asked people follow-up questions about the notion of getting rendered catatonic in an experience machine. Don't you think they'd reply that they find it unsettling, disturbing, creepy --- or in Utilitarian language, unpleasant? I'm pretty sure they would. And if they do, their preference isn't between pleasure and something else, but between different flavors of pleasure. Your debilitating experience machine is really just a new angle on
an old point of John Stuart Mill's: "It is better to be a human being dissatisfied than a pig satisfied; better to be Socrates dissatisfied than a fool satisfied." Happiness comes in different flavors. You prefer bitter orange, I prefer chocolate fudge. Tomeydo, tomuhto.

Everybody, tautologically, prefers what he or she prefers. Our job, according to preference Utilitarianism, is to help everyone satisfy their individual preferences to the best of our ability. This ethic does
not raise the problems you describe: We
can, admittedly within limits, observe people's preferences. We can also observe whether our private acts and our public policies satisfy their preferences. And having done that, we can
change our actions and policies to satisfy them more.
Preference Utilitarianism is hedonistic, or at least consistent with hedonism, in that it follows from joining
psychological hedonism with ethical
hedonism. As you know, psychological hedonism is the view that people prefer what they prefer because it pleases them more than their alternatives. Ethical hedonism is the view that increasing pleasure is the greatest good there is (maybe the only good). Put the two together, and you get the normative theory that to do good is to increase people's preference satisfaction. And although the theory's origin is hedonistic, it no longer depends on the precise internal state of mind that we ought to maximise for. Is it physical pleasure, as the hedonists say? Is it peace of mind, as the eudemons say? Is it happiness, as the Utilitarians say? No matter. All we have to look at is people's external behavior.
