Yeah, hold on... let me compare the costs of enriching a billionaire parasite piggybacking off publicly-funded programs that developed all the technology said billionaire parasite is piggybacking off with said publicly-funded programs.
No, Clyde, it was cheaper - because we actually got results other than merely enriching a billionaire parasite.
Your brain has been so addled with "free market" fairy tales that you might just as well believe a glass slipper will magically turn you into royalty. There is absolutely nothing parasites like Musk can do that we couldn't do far, far better, much more efficiently and far cheaper through public means - and that's it.
