The major “freedom indices” are polluted neoliberal ideological wankery that shouldn’t be used to settle a bar argument let alone decide that it’s totally fine to do away with large cash transactions.

Even limiting things to strictly “financial freedom” - while more germane to the cashless question and also happen to stick the US above all of Europe save Switzerland - are highly questionable due to the inclusion of weird subjective metrics like “labor regulations = less freedom”
