Gravity makes things that are more dense fall. If we extrapolate this fact through the entire Universe, we can imagine Ordinary Matter falling more than Dark Matter, and Dark Matter falling more than Dark Energy.
From this perspective, can we think of Gravity as emanating from the repulsive “push” of Dark Energy, rather than an attractive “pull” from Matter?
This is referred to as the Le Sage theory of gravity and is generally discredited because of a whole slew of problems with the concept, most notably drag
This can't be the sole answer to the problem of gravity, because a model like this would make modeling the solar system difficult -- if you eliminate the gravitational force from ordinary matter and replace it with a repulsive force from dark matter, where do you put the dark matter so that every planet and asteroid in the solar system obeys a $GM/r^2$ force law? We know that the answer can't be "in a shell at some great radius" due to Gauss's law, which also tells us that the answer can't be "distributed uniformly through the solar system", because this would give a different effective mass for Jupiter than it would for the Earth.
So, you still need ordinary gravity to explain the solar system. So, then we'd be using this repulsive dark matter to explain the stuff that ordinary dark matter does, but why would we posit an exotic gravitational force for something that we can already explain with ordinary dark matter obeying an ordinary gravitational force?
Of course it could, that much is clear. The typical response from cosmologists is to introduce fudge factors such as dark matter, dark energy etc instead of acknowledging that relativity has been discredited. Realtivity is unfalsifiable because problems are explained away with the aforementioned fudge factors. Dark matter explains the drag and other problems observed at a large scale.
