I think that one way to generalize this preference would be as follows:

"The Utopia should allow me to voluntarily -- and temporarily -- limit my own capabilities if I so choose, but it should never impose limits on them. In fact, the Utopia should provide me with vastly enhanced capabilities, if I so choose."

Thus, you could voluntarily turn down the gain on your Omni-Sensors when browsing the Farmer's Market, while knowing that you could turn them on at any time. Simliarly, you could disengage your Anti-Grav Flight Module in order to climb a mountain, as long as you knew that you could turn it back on at a moment's notice (or even faster than that).
