Instead of delivering a vessel that can support earth-based life for hundreds of millions of years, we just have to deliver about 100 kg of Von Neumann probes and stored people, which build more of themselves.
We don’t necessarily need stored people. The probe can unfold into basic infrastructure + receiver, and the people can be transmitted by some communication channel (radio, laser or something more exotic).
