I think one idea is that there aren't very many habitable planets. The Trisolarians are coming to Earth because it's their only option, not because they want to destroy humanity.
Then it's even weirder. Detecting planets around stars is trivial, yet nobody is running to get that prime real estate?
Still makes no sense.
