Is your use of "armchair logic" a criticism of the theory that Io is volcanic largely because of tidal energy? I often wonder about the results of planetary geology. Even the interior of the earth is still not very well understood, and most of the methods we use to understand it (e.g. seismometers) are not yet usable outside earth.
