How about this. What holds quarks together? Electrostatic force. Because charges in a line: +2 -1 +2 Will be pulled together, not pushed apart. If coming from infinity they will reach the speed of light at some distance. Hand wave some relativity now because our Hadron just became a sort of black hole. Are they orbiting inside, outside, on on the event horizon. IDK but... These orbiting charges create a magnetic field. What holds a nucleus together? Magnetism, along with some particular interaction of the quark charges similar to the above. Some very complicated dynamics going on.
