Imagination is not reality. Reality have constraints that can be so complex that can be really hard to imagine. This is why we run simulations on computers when it comes to lets say weather and not do thought experiments only. I can even give a real life example here. I am from Poland. And at this moment we are facing a coal shortage (which will cause energetic crisis in the winter) while sitting at the same time atop one of the largest coal deposits in the world. No one could imagine this as a possibility a mere year ago.
