By the way, I do NOT believe that observations necessarily point to low altitude heating. My view is that observations are consistent with both low altitude and high altitude heating. Perhaps this should be a topic for Loops IV.

There is no way around to heat up first chromospheric material to fill coronal
loops to produce the enhanced soft X-ray and EUV emission we see from
coronal loops (like in flares). Any heating mechanism that heats directly
in the corona, does not increase the local density, so we would not see
