The really nice thing about tank farms in space is that people can live in
the tanks, safely!

the three pillars are

1) lots of water up there, as cheap as possible - big one shot boosters just

2) use the boosters/tanks as habitats as well - dual use designs that look
like the enterprise on the INSIDE
and never return anything....
