I'm not so sure this is true. Public-key cryptography, for example,
relies on it being easier to check that two primes multiply to a given
number than it is to actually obtain the answer by factoring that
given number. Wouldn't zero-knowledge proofs[1] provide a basis for
information as currency? It allows people to verify the authenticity
of information to a desired degree of certainty, but wouldn't let any
of the information leak (which would 'devalue' the possessor's asset).
