Are you being facetious? If not, all you do is to turn the two terms around, making "freedom" the absence of constraints and "liberty" constrained freedom. Either way, one entails constraints and the other does not, so one is a coherent value for a society and the other is not. That's the point: there can be no such thing as a viable society based on a 'value' of unconstrained human beings, whatever word might be used to signify it.
