A universal measure for anything is a big demand. Mostly we get by with some sort of somewhat-fuzzy “reasonable person” standard, which obviously we can’t fully explicate in neurological terms either yet, but which is much more achievable.
Liberty isn’t a one-dimensional quality either, since for example you might have a country with little real freedom of the press but lots of freedom to own guns, or vice versa.
What you would have to do to develop a measure with significant intersubjective validity is to ask a whole bunch of relevantly educated people what things they consider important freedoms and what incentives they would need to be offered to give them up, to figure out how they weight the various freedoms. This is quite do-able, and in fact we do very similar things when we do QALY analysis of medical interventions to find out how much people value a year of life without sight compared to a year of life with sight (or whatever).
Fundamentally it’s not different to figuring out people’s utility functions, except we are restricting the domain of questioning to liberty issues.
