This document proposes building a 1 million member interstellar volunteer community called Starfleet to help make interstellar civilization inevitable. It argues that narrowly focusing on technological capability alone to reach the stars is "easy but dangerous", while broadly building cultural infrastructure for an advanced Kardashev Type III civilization is "hard but safe". Starfleet would be structured into units focusing on areas like science, engineering, culture and policy. Members would earn "star miles" for contributions and advance in rank. Funding would come from membership fees and sponsorships. The goal is to recruit 1 million volunteers over 10 years using existing networks, space communities, and original science fiction content.
