Again, the inventor of memory foam isn't going to hide it, they are going to create products out of it or license it. So the idea that NASA "shares" is immaterial. Calling the SLS "not ideal" is like saying a Tsunami will get you wet. SpaceX benefited as much from NASA as NASA benefited from the Nazis, and as the Nazi's benefited from Goddard. Research marches on. But currently the most important R&D in the space business is being done by SpaceX. The only way space travel becomes economically viable is through re-usablity, which NASA has not made any credible attempts at solving. And NASA isn't inefficient because it's not a business. It's inefficient because it's being used to distribute pork barrel spending to specific congressional districts. If the most efficient way to build the SLS was to build it in Puerto Rico, it would never happen because Puerto Rico doesn't have any congressional votes. Instead NASA is forced to break up projects across a massive number of congressional districts and do each sub-task in the most costly way possible so the sub contractors in those districts get a big taste of excess profits to spread around the district.
