I mean, both have a big role to play. You mention rocket tech, which is a perfect example of the strengths and weaknesses of public and private enterprise. Public enterprise can be great because it enables societies to leverage huge amounts of capital (at one point, the US was spending 4% of GDP on the Apollo program each year--the equivalent of $1 Trillion/year today) to accomplish goals that are beyond the capacity of private industry at the time. It suffers from being totally divorced from the normal constraints of economy, and so tends to way overspend (4% of GDP is frankly insane) and to get stuck at local maxima (see SLS). Private enterprise is basically the opposite. It can never match the government in terms of spending big to pull tech forward by decades--the profit margin doesn't really work that way. But it lavishly rewards the efficient allocation of capital, which (so long as there is meaningful competition) creates a drive to constantly improve tech. It's painful to think about where rocket tech would be without the recent advances born of private capital!
