You're confusing area with volume. There is plenty enough material in our own solar system to build something with sufficient area to block all the light from the sun. It would be relatively thin. A large number of small, natural bodies works for the same reason.
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
