I seem to recall the UK Brexit and that freewill argument was almost immediately challenged by calls for next rounds of referenda ( presumably until the right decision is reached by the population ). As always, it is democracy and free will as long as it is exercised in a way the conforms to rather specific view of what the outcome should be.
I don't understand your argument. Britain voted to leave, and they left.
People can 'call' for whatever they like. In this case the demand was related to the refererendum being on a nebulous idea without any clear idea on how to implement it. No-one would ever seriously suggest having a referendum on a Trade deal or Treaty before the negotiations had even started. The idea of having a referendum on the final deal was hardly a crazy one.
