I forgot to talk about the example of the quarks. That one is only there for spectacle, to dazzle, but it has even less content than the others. That counter intuitive fact only relies on the ignorance on the phenomenon and the fact that the manifestations of the consequences of energy and mass being the same thing are not an everyday experience as oppose to the additivity of mass. It only show that intuition relies on experience. It is the same if I, that have never surfed before, try to surf. I can try to use my intuition all I can and pretend to be a jedi and use the force or the flow but I will not be able to ride a wave. Not until I have passed through the experience a number of times (although I am less hopeful in my case).
