The comparison to those stupid boondoggles doesn't really do the scale we're talking about justice. A few percent of gross world product is 4 trillion dollars per year. That's more expensive than the entire Second World War. That's enough money to fund NASA for two centuries. That's enough money to launch the mass of the empire state building into LEO twice using current disposable rockets.
