It isn't, provided you have some sorta biological immortality and/or suspended animation - also take into account what relativistic speeds does to the traveler. It takes a lot less time for the crew to get from one point to another, from their perspective. You can get to such speeds as to make an exponential difference in that regard, at a comfortable 1G acceleration, in a reasonable time frame (just don't ask about the energy costs required to keep that up).

Does mean everyone they know in love is either a lot older or dead and their old world radically changed, even if it was only a few years for them... But generally, if you're off colonizing worlds, the idea is you're leaving your old life behind anyways.
