The person you are responding to wants for agencies to be able to exist, not to destroy the US government & society.
"Significant source of problems" that what, we have health care and clean air? You indicate your desire to tear it all down & that's what we are seeing everywhere, but why, and for what? It's so unfathomable, so unclear that "we would be much better off" to not have the world's best institutions as we do, the greatest science the best education, the world's leading medicine.
It's so unclear what drives this destructive anti-government fervor to me. You've given me not even a single remote small hint. Neither had this administration as they have, as barbarians, come in and chainsawed as much as they can down. For what? What makes people so opposed to a society? Wanting so badly to make sure there is no government, no services, no help, no collective will?
