Everybody gets their back up when defending their favorite tax sinkhole. TVA, CDC, FDA... there's always some more-or-less explicitly unconstitutional federal agency to which Joe or Suzy Taxpayer secretly scribbles love notes on the back of their Tea Party-issue Gadsden Flag post-it notes.
Even the most Heinlein-quoting, Ayn Rand-lovin', taxation-is-theft Wookie suiters get all weepy when NASA takes a shot in the payroll, when the simple fact of the matter is that the only spaceships the federal government has any constitutional business building should be run by the USAF and have frickin' laser beams on them.
It's a good thing NASA didn't exist from the nation's founding, or Lewis & Clark's canoe would have taken thirty years to build and contained strips of birch bark from 72 different Congressional districts. If we want to see progress in space, we need to tell NASA to go research airfoil shapes and just declare everything that happens above X miles to be extraterritorial and tax-free.
They’re worried about funding the ISS? Auction it off. You don’t think that people will pay big bucks to go gambling in a casino with zero-g hookers and blow? It'll be the only way to get regular folks into space, too, because they're not going to pay astronauts to mix Long Island iced teas in those weird drinking squeeze bulbs.
