It's because SpaceX and Tesla are the clear leaders in opposing the de-industrialization trend in the hyper-financialized American economy. It's so incredibly stupid and short-sighted to move manufacturing and the associated technological R&D outside the United States, as it results in the loss of critically important technological skills. Follow that route and you end up with financial institutions desperately trying to retain control of technology via intellectual property lawsuits targeting countries with their factories in China, which as history has shown, will alway be a losing battle.
Rolling back the financialization of the American economy, and re-introducing industrial activities at scale, is the only way the country will avoid devolving into a dystopian Third World system of wealthy enclaves with large capital holdings (protected by private security armies) surrounded by miles and miles of festering slums.
