    The electron pressure is always there.

    But you are right regarding the thermal energy making fusions easier, which can happen at any pressure or density with enough velocity. At this point I am not even sure which of the 2 approaches (cold and far denser or hot and far less dense) would be “easier”, where we would have to first define what easier would actually be…

    Heat means more vibrations, which means less density and more force needed to compress the matter to the same density. Just compare any solid material to plasma. Or the 100 million kelvin plasma at ITER, which has an absurdly low density (like a high vacuum) but still 1 bar of pressure due to the thermal pressure.

    Electron degeneracy pressure is always present when there are electrons, regardless if they are part of an atom or free moving in a plasma.
