Sort of, "dark matter" would just be matter that doesn't interact with photons. We're pretty dang sure dark matter isn't neutrinos but for reference neutrinos don't interact with photons either, so it's not like dark matter is actually all that exotic. We just can't constrain every thing about it.
What it comes down to, and this paper doesn't change this at all, is that either there's a bunch of matter we can't see or force carrying particles don't obey basic geometry (or the universe has much weirder geometry than we think). Most of us are a lot more comfortable with basically invisible matter.
My understanding is that our Universe is endless in all 4 dimensions and in scale. Every point of Universe contains infinite number of small, even infinite small, particles. These particles are forming large objects, even infinite large objects. And these objects are oscillating endlessly: condensing and evaporating, so whole Universe cannot be sink into singularity, even in endless time.
IMHO, we are in large bulb of plank-scale particles, which are called "physical vacuum", which are forming medium for all other particles and forces to travel. This medium is not regular: it denser in center (so it causes red shift), it denser around massive objects.
Every particle is composed from smaller particles, which are floating in a medium (field) formed by much much smaller particles. And this pattern repeats endlessly at any scale.
So there no particles, only fields OR there is no fields, only particles.
