The discussion is about the following justification of the claim in the provoking answer of the title question:
The energy density of gravitational fields is negative. But a negatively definite energy density must not exist. Therefor gravitational energy density is compensated by dark energy density.
The dark energy density is omnipresent and extremely strong because it even must compensate for the energy density of the gravitational field at the surface of neutron stars.
Gravitational fields cause a depression or a dent in the dark energy density. If that dent moves, the dark energy must flow around that moving dent. That flow contains some energy, which must be provided by the kinetic energy of the moving source of the dent.
The energetic activity inside of stars transfers a lot of kinetic energy to the dark energy. This additional energy leaves the star in a flow. This flow implies a gradient in the dark energy density. This density gradient has the opposite direction of the gradient caused by the gravitation of the star mass.
It therefor shields the gravitational effect of a part of the star mass. This shielding ends after the energy density in the flow has reached the background energy density.
At the critical distance from the source of the flow, where the flow ends, the gravitational impact, which has been shielded, appears.
This appearance is falsely interpreted as dark matter.
