The classic solution to the problem would be to establish a market in privacy because it is the most efficient known mechanism for allocating valuable items. If one could know the true costs and benefits of keeping a secret then most rational consumers would choose the level of privacy that suits them. However, this runs counter to the basic instincts of bureaucracy. For example, the European high court has decided to give a relatively obscure bureaucrat in Paris to the mandate "to lead an increasingly powerful group of European privacy regulators" to decide who gets access to what.
