Earth Sun L2?

The Earth-Sun L-points (all of them) are pretty well useless since as
of yet astronomers have found only dust there.

Do you really want to build any sort of space structure in the middle of
a dust-storm? It's going to make a heck of a mess of the paintwork.
Although there's a theoretical benefit for stationkeeping in a lagrange
point there are practical problems. If you have the energy available
then using some of it to move to a nicer neighbourhood seems to be
sensible to me.

I don't know if the appellation "dust storm" really applies. If I
understand correctly the movement is pretty leisurely in the L4 and L5
points. Also the density is probably pretty low too. In any case,
there isn't anything of value there aside from a stable orbit. The
Moon-Earth L-points at least have the advantage of proximity to the
Earth and Moon. The Earth-Sun L-points do have that same advantage, to
a lesser degree. They always stay a fairly regular distance from the
Earth, so while that distance is large, at least it isn't subject to
much change. This makes them a fair spot for unmanned observation type
satellites that would want to be away from the interference of Earth
transmissions but still be in range to communicate.
