A stupendously anthropocentric viewpoint on the priorities of
ET species economies. It is no strain to imagine, perhaps on
a planet where multiple intelligent species evolved, or where
competition for reproductive success, and/or new territory for
one's offspring became a very powerful instinctive drive, a
technological species whose need to spread their descendants
onto every available solid surface in the universe became as
strong as the sex drive is in humans. What is possible in an
economy is all about priorities.


If you prioritize space travel over food and medical care, you don't
survive. If their reproductive drive is that strong, it will lead
them to destruction, not successful colonization. Just wanting to go
to space really really badly won't make space travel economically
sustainable, call it sex drive or call it anything else. If the
physics isn't there, it isn't there.
