If fussion propulsion is possible, probably fussion would be available for energy production on Earth, and that would imply “energy too cheap to measure”. The kind of economy under that regime would extremely different from ours. Under that conditions, for example, materials would be extremely easy to obtain from Earth (we could profitably mine minerals with far lower ore grades than we can now).
I think that if we ever reach the “energy too cheap to measure” economic regime, for example, extiction risk would be far lower than now. But we all know that Brazil is the country of the future, and allways will be, and that nuclear fussion will allways be 30 years in the future either… I hope I am wrong in both :-)
