In the book, the trisolarans aren't coming to earth just because is the only habitable planet, it's because it's the closest one too. The don't have FTL and they spend the full resources of their dying civilization to build a fleet that will reach earth in ~400 years.
So yeah, a lot of prime real state but no way to reach it.
- cyberax 2mo ago400 years is nothing. At this speed, all the Galaxy would have been colonized long ago. This subplot in the book is at least reasonable. Somehow aliens capable of pico-scale engineering can't make a telescope to observe the nearby solar systems, but OK, whatever. Cultural blindness and all that. It's the later plot with the "dark forest" that makes no sense. There are ships capable of moving at relativistic velocities and spacetime-altering weapons.
