Since the advent of capitalism and the expansion of the market economy, we have a number of institutions, rules and procedures that determine what can be done with a whole range of resources, artifacts and goods. The institution of private property, based on a whole series of legal corpus and an effective coercive apparatus, allows a natural or legal person to be granted the rights of ownership of a particular good, and this person in the exercise of his or her individual freedom and autonomy and within the space that draws the "legality" can do what he or she wants well; consume it, give it away, sell it. The economic philosophy, already from the famous Mandeville Fable (1670–1733), assures us that all pursuing our particular benefit came to the maximum collective benefit (sisi pués cada parte was full of vices, but todo el CONJUNTo was a paraiso), which already takes the "invisible hand" to assign resources appropriately.
