There are practical and political problems with paving Arizona with 
solar panels.  For example, the locals may object.  The same is true 
of putting in an area of solar panels equal to the area of the roads.

Some people, most recently a certain Mars fanatic, don't see the 
value of reducing the cost of getting to GEO from $20,000/kg to 
$100/kg especially when the traffic model is a million tons a year.

I won't say this will automatically lead to space habitats, but a 200 
to one reduction in the cost has got to make it easier.
