Can a Security Token Ever Transition into a Non-Security (Utility) Token?

Yes, it is theoretically possible, primarily by achieving "sufficient decentralization." If the network evolves to a point where no single entity's managerial efforts are crucial to the token's value, and its primary purpose shifts to consumptive use, the token may cease to meet the Howey Test criteria and no longer be considered a security.
