You can transport a qubit via quantum entanglement, yes. That's totally a thing. This might be useful for things like quantum encryption. If that's all you are saying, great. You seemed to be implying that it can replace the current internet and we no longer need fiber optics, wires, or other forms of classical communication.

First, to transport a qubit, you need to send an entangled particle first. This is usually done with fiber optics. You could also send a bunch of particles in traps on a truck, or over the, air, whatever, but you still need to exchange particles for quantum teleportation. Once you've exchanged entangled particles, you can use them to transmit the quantum state of another particle. This might be useful for quantum encryption, but you could just use the originally exchanged particles instead.

Second, you've already stated this, you cannot transmit classical bits. You'd still need all the original Internet infrastructure to transmit classical information. Things like, the British are coming, a funny cat gif, any message really. In fact, entangled states are actually useless without transmitting classical information about the partner particle. Without that, it's impossible to even detect that the particle is part of an entangled pair, much less use the information for anything. The quantum eraser experiment is a great example of this. Without the information about the other entangled particle, all you get is a screen showing that the particle always went through a single slit. Once you know the which way information about each particle, you can separate them out into two interference patterns that cancel out.

Now, there may be something that connects particles quantumly that can be used for communication. Such a thing is not currently part of quantum mechanics and isn't quantum entanglement, such an effect would need some new name.

Regular matter clumps together to form gas clouds, stars, black holes, planets, etc. In general, matter collapses. This happens because particle interactions and collisions generate heat that gets radiated away. Without a mechanism to lose energy, gravitational collapse isn't possible. When we look at galaxies, the stars, gas clouds, etc, tend to fall inward as they lose energy and more matter gets towards the middle than the outside. In spiral galaxies, you see a huge bulge of stars towards the middle. When we look at how fast they rotate, we measure that matter is distributed more or less evenly across the entire plane of the disk. This measurement is really what kicked off our current understanding of dark matter followed by many other discoveries regarding matter distribution.

If dark matter formed stars, planets, gas clouds, etc, like normal matter, it would clump towards the center of galaxies, just like normal matter.

Anyone can theorize whatever they want about the universe, and should not be discourage from doing so. But if your theory makes claims based on current understanding and observations, but the knowledge of that current understanding and observation is incorrect, it seems logical to help that person along. If you want to base your new theories on what is currently understood, it will benefit you greatly to learn as much about current understanding as possible.
