WISP and Musk are ruled by the same Shannon, so I'm skeptical that there will be a significant advantage over the long term, but satellite has a big advantage it terms of coverage -- the difference between "can you see that tiny hilltop in the distance over the trees?" and "can you see the sky?"

Same Shannon limit, but very different bands and channel sizes as well. Most WISPs are limited by the unlicensed frequency bands that exist in FCC part 15, and things like 3.5 and 3.65 GHz. One of the things that can go wrong with that is many WISPs in the same area fighting over the same bands from 5100-5900 MHz.
By comparison LTE fixed last mile services in some places (where expensive spectrum is owned by entities like tmobile) have some of the prime tree-penetrating frequencies in the 600 and 700 MHz bands, and 2.5 GHz band. One of the reasons why clearwire was acquired by sprint was for their 2500 band.
