Living on a single planet or solar system is suicide in the long term. Asteroid, Gamma-burst, anything can kill your habitat. There is no technology than can protect against a gamma ray. I suppose.

I read the pdf diagonally cause it's written with obfuscation and unhelpful specialist jargon. So I dont remember if it address the problem , but one popular solution to FP is exactly what you said: Intelligent species do not need to colonize its galaxy.

The problem of most of FP solution (and also this one) is that (as the pdf say) you cannot test them. If you cant test them it become a matter of faith, so not really helpful.
