Even if that's true (and in the age of the Internet, that's far from certain), you don't have to transport the whole civilization at once--you can create it from scratch in a century or two starting with, say, 30 or 40 young, healthy, genetically diverse women and a big dewar of sperm. For the first few generations you only need enough technology to survive, breed, and educate.
