Sara Silverman wants to end world hunger (and get those disturbing images off her 48inch plasma TV). Her solution: sell the Vatican and use the proceeds to feed the world.
This is good, but only second best. The buyer who values the Vatican the most is in fact its current occupant. So selling the Vatican would lower its value. (It is true that the new owner knows he can sell it back to the Pope and takes this into account when deciding how much to offer. However, this adds needless transaction costs, plus the Pope will have bargaining power in the resale which would not be internalized by the buyer.)
A better idea is to give the Vatican directly to the poor and allow then to charge the Pope rent. Subject to this small ammendment, I wholly endorse the following (although the bit about the Holocaust may require the consent of more than just Ms Silverman and me.)
