Dark matter isn't even proven yet.
You’re right.
One counter theory (oops, “hypothesis”) is that the “missing matter” is actually the stored gravitational energy of systems “weaving” among themselves (my wording.) kind of like how intense magnetic fields “braid”, in a galaxy scale all mass bodies are not sitting evenly dispersed on the orbital plane (by accretion,) rather they are perturbing each other in complex orbits as the disc churns, storing more gravitational potential than may be visibly accounted. Like a spring (compressing a spring actually increases mass.)
Galaxies without these complex orbital currents would correlate more consistent visible mass estimations.

I definitely feel there is something else going on, but am not qualified to say how. Dark matter seems a heck of a large hook to hang much of cosmology on. Maybe it is real, maybe not.
So true! Just to show how much so, here’s another hypothesis!
Time dilation! As time itself emerges from space/gravity, mass and distance could introduce a “time dilation” fudge that cosmologists attribute to “dark energy/matter”!
It may be our lack of understanding of time itself that changes factors of how we calculate the cosmological expansion/contraction and other mass stability estimates.
I too find it funny that we can wrap up our ignorance into a concept and call it dark*(whatever)!

My 2 cents : I have also a simple idea about time dilation explaining the dark matter, but I did not look out for numbers to check if it's plausible. Simply put : the center of a galaxy is the most massive part, often hosting a blackhole, and it's so massive that time runs slower than the outer part which is lighter, giving the impression on the outside (us looking from far away) that the galaxy rotates at the same speed in the center and in the outer part.
