So despite having satellites in orbit being a clearly profitable business, no group of people would have ever gotten together to develop rocket technology (which really was first developed for warfare to begin with...)? Capitalism does not forego cooperation. I won't claim it is always the best or most efficient solution possible, but saying that groups of people working together out of selfish motives is incapable of achieving such success is kinda out there.
I showed you something that goes way beyond the concept of satellites, and it happened over 43 years ago. Sure, capitalism can achieve things, but it will always be well behind a hugely concerted and unified effort. Furthermore, capitalism is divisive, both physically, and socially.
Oh, and watch the video. Turn the volume up. It's quite a meditation.
