The US government (these days at least) is perfectly happy to let private enterprises take on the costs and risks. They'll just contract it out. You see the same thing across the entire intelligence and defense sectors (some major systems are maintained not just by contractors at military facilities, but at facilities owned and operated by contractors).
Space launch is a contemporary example of an important capability that the US has demonstrated they're happy to mostly hand off to private enterprises (mainly SpaceX these days).
