In graduate school, if not earlier, physicists learn to let

think about what counts as "understanding". Knowing the
equations and how to apply them is the real understanding.

No, it means that if I find a fundamental process underlying gravity,
like entropic gravity, I will just have moved your problem down to a
different one, why does matter produce this entropic gradient that
produces gravity. Physics doesn't answer "why" questions about
fundamentals; otherwise they wouldn't be fundamental.
