The marketing of Liberty is enclosed with the formula “Liberty + Responsibility.” It is some sort of “you have the right to do what you please, BUT you have to be responsible for your choices.” That is correct: the costs and profits enable rationality to our decisions. The lack of the former brings about the tragedy of the commons outcome. In a world where everyone is accountable for his choices, the ideal of liberty as absence of arbitrary coercion will be delivered by the resulting structure of rational individual decisions limiting our will.

The couple of Liberty and Responsibility is right BUT unattractive. First of all, the formula is not actually “Liberty + Responsibility,” but “Liberty as Absence of Coercion – What Responsibility Takes Away.” The latter is still right: Responsibility transforms negative liberty as “absence of coercion” into “absence of arbitrary coercion.” The problem remains a matter of marketing of ideas.

David Hume is a strong candidate for the title of “First Behavioural Economist,” since he had stated that it is more unpleasant for a man to have the unfulfilled promise of a good than not having neither the good nor the promise of it. The latter might be a desire, while the former is experienced as a dispossession. The couple “Liberty – Responsibility” dishes out the same kind of deception.

It is like someone who tells to you: “do what you want, enjoy 150% of Liberty”; and suddenly, he warns you: “but wait! You know there’s no such thing as a free lunch, if you are 150% free, someone will be 50% your slave. Give that illegitimate 50% of freedom back!” And he will be -again- right: being responsible makes everybody 100% free. Right – albeit disappointing.

Perhaps we should restate the formula the other way around: “Being 100% responsible for your choices gives you the right to claim 100% of your freedom.” Only a few will be interested in being more than 100% responsible for anything. But if it happens that someone is expected to deal alone with his own needs, at least he will be entitled to claim the right to his full autonomy.

The formula of “Responsibility + Liberty” is associated with the evolutionist notion of liberties, which means rights to be conquered, one by one. Being responsible and then free means that Liberty is not an unearned income to be neutrally taxed. It is not a “state of nature” to give in exchange for civilization, but a project to grow, a goal, a raison d’etre.

Putting first Responsibility and then Liberty determines a curious outcome: you are consciously free to choose the amount of freedom you are really willing to enjoy. Markets and hierarchies are, then, not antagonistic terms, but structures of cooperation freely consented. Moreover, what we trade are not goods, not even rights on goods, but parcels of our sphere of autonomy.
