Diversification

From: George Perkins [mailto:cygonaut@...]

So there is really a need to trade with earth. We stand to gain, or
achieve good equity, by so doing.

And discussion of the prospects for two-way trade keeps it a real-world
discussion.

Many Mars advocates go on about how Mars could be made totally independent
of Earth. They feel the necessity to assume this since Mars seems to have
very little that Earth would need. But total independence is not what makes
civilization go. It's different communities which have different things to
sell to others, and which need other things which other communities can sell
to them in turn.
