They are to few to spawn a large enough market.

Ah ha.  Somehow I don't think we need to spend 100's of billions to figure out
ways to save tens of billions.

Well their are similar treaties for space, but that doesn't really mater.  If
there was money on the line those treaties would go the way of their
predisesors.  The big problem is they all proved not worth the bother.  So
Arctic bases arew maintained for political reasons (so all claiments keep
rights to Antarctica in case they want it in the future) and the undersea labs
have all been pulled out or sold.
