SpaceX means either lesser tax money spent on space travel for same output or more space travel for same budget. Isn't that enough impact already?

I'd actually argue it'd be better if SpaceX could gobble up more taxpayer money; they are far more likely to use it for research/development/innovation than either costPlus space contractors or other parts of government that would be allocated the cash saved by cheaper SpaceX launches.
