Things we need desperately to preserve freedom...
1. Cheap Access to Earth Orbit
2. Ability to identify life bearing planets
3. Warp Drive

Allow me to add one: a technology which will provide 100% self-sustained living in space. A closed system with air food and water, all cycled within the habitat. The technology could be used for permanent settlements or for long distance long term travel.
