Kind of like welfare for Astronauts? Is that your proposal?
more like:
lunar mass driver, to take the ULTIMATE military high ground
strip-mining the moon, for materiel to build orbiting solar collectors for energy needs of Earth
terraforming Mars, to get some of the eggs out of the current one basket
stripmining asteroids
etc...
oh, don't worry: some of the profits would come back to fuel "pure" science... say, to build the biggest parabolic-reflector telescope you can think of in one of the craters on the far side of the moon, so the time-voyeurs can get their jollies while the rest of us make some actual USE of space.
