I think you will find that Penrose claims that gravity has something to
do with why macroscopic mixed states are not observed. His opinion is
not shared by the majority of physics, but I think it's safe to say that
this area (and others with which Penrose is concerned) is still unclear,
even to conventional physicists. (In other words, even if people don't
agree on the solution, most agree there is a problem.) However, IIRC
the mass at which gravity influences QM was 10^{-5} gram or something
like that---tiny by our standards, but way above the "molecular level".
