All that assumes two things for which there is no strong argument. First, that an extraterrestial intelligence would only be interested in traveling to another planet because it detected signs of intelligent life there. But why would that be? Why wouldn't a "life friendly" planet be almost as interesting? Suitability for life, and likely even the signal of the presence of life, is something you can get from spectral observation.
And second, intelligent life may or may not care a great deal about the time of travel. No reason intelligent "iife" elsewhere should not be self-constructed to be indefinitely patient and repairable.

While you can get a lot of information from spectral observation, most of the universe isn't close enough to observe it. The earth is young enough that even if we assume infinite magnification most of the universe cannot observe it as no light from earth has reached them yet.
