100% freedom is an absolutely banal phrase.
What does it even mean? I am pretty sure that you don't mean someone is 100% free to murder someone else. So you clearly believe in some restrictions.
I can already imagine the counter argument: "Well, 100% freedom unless your freedom infringes on someone else's freedom!"
Ok, but what does it mean to infringe on someone else's freedom? Murder is the easy case; what about polluting a river? I think we would all agree dumping enough chemicals to kill all life in a river would be infringing on other's freedoms, so lets prevent that... but where do you draw the line? It will take judgement, consensus, and compromise to find out where that line is.
So suddenly we are back to needing rules around curtailing freedoms that some people aren't going to like.
