Economic freedom is like free speech (and any other freedom, really). It can not be absolute unless everyone behaves in good faith, once you assume you have rogue players who exploit the good faith behavior of others you have to have rules.

So you will find literally no place where absolute freedom is practiced, and for good reasons.

Sadly, in case of economic freedom a rogue player who has billions can also have political power to lobby against inconvenient to them rules, and ah everyone wants to be on their good side.
