Well, "take over" is prob not the best term to use in that instance, what I meant is that people be happy about private enterprise attempting to do things governments haven't touched in a good while. Has NASA made successful reusable rockets in the past year? Lol not with their current funding.
I'm all for more NASA funding, but I'm all for commercial exploration of space, too, and the moment governments start going "o hey, private enterprise, you evil creature, we want to regulate you" is the moment in which progress grinds to a halt.
Now, what is currently happening is exactly the opposite of what certain politicians sugest should happen (IE complete takeover by private companies). NASA can totally work side by side with spaceX or any other company to explore space. Hell, they kinda already are, which is a great start, since it means more investors for private companies and less of a burden on NASA to get cargo into space, so NASA can focus on more important matters such as probes and experimental projects. Maybe one day it'll be like hiring a truck to transport your fancy equipment somewhere, except it'll be NASA hiring private companies to deliver their missions to the desired locations, which is kind of already happening.
