Spent a few hours studying SpaceX's technology, ecosystem, and logical closed loop. The most impressive thing about SpaceX is that, like Bitcoin, it's nearly irreplaceable in the global market. Even if any country/region in the world uses its entire national power to create a fully identical and functionally equivalent alternative, it would only become that country/region's 'SpaceX' and not the 'global SpaceX.' Mark my words, as of now, it's almost impossible for any country, even with its full national effort, to replicate SpaceX's 'global ecosystem + commercial closed loop + iteration speed' within the next 100 years.
