>But perhaps they're advocating a return-to-the-Earth philosophy
Indeed. Not quite as far back in time as you sarcastically suggested, but down-to-Earth enough that Congress stops enjoying absolutely abysmal approval ratings and President Reagan's infamous line of "I am from the government and I am here to help." stops resonating so strongly as a prime criticism.
If we also have to destroy ostensibly useful institutions like NASA to achieve it, well then so be it. As I mentioned in a sibling comment, the chances for more amicable processes have come and gone.
