I agree in part.  But it is very geocentric to think that just because it
makes sense to us, that it automatically makes sense to ET.  For
example, what if ET lives in an aqueous enivironment or on a planet
with a very dense atmosphere?  Under those circumstances, neutrinos
travel faster than light (the speed of light is slower in water and air).
Neutrinos can also travel through the core of their planet and be totally
unaffected!  Who needs satellites when neutrinos have no line-of-sight
issues and cannot be blocked or jammed?  So it may not make sense
for us to use neutrino communication, but it may make sense to some
other ET species.
