It seems paradoxical. Access to amounts of matter and energy that would be absolutely transformational to the world (solar system) economy... but no economic case to go and get them? Perhaps this is something with a huge payoff that doesn't make investing sense on anyone's time horizon because it's longer than all our lifetimes. Still, long-lived entities (such as nation states) do exist - depending on political conditions, projects on multi-lifetime timescales can be viable. One would like to think that our far-sighted leaders would make some investment, given there's an awfully big prize up for grabs.
