Show me where Joan Baez has created something half as beautiful and complex as Pet Sounds or Smile.  Not bad for the "shallowest man in the world".  I can't speak to his personal troubles and excesses, but I judge artists by their work and here Wilson succeeds with flying colors.

Har, har.  It includes alternate stereo mixes (the rest of the album is in mono) and a couple of outtakes.

Certainly not!  The Smile cult has been building online for the last 15 years and I know lots of people who have been working with these fragments, trying to construct their own ideal version.  Now we have all sorts of new pieces and parts to play with, in pristine audio quality.

To be fair, there was a certain infantile aspect to Wilson's work and Smile in particular—trying to recapture the innocence and wonder of youth through music.  It comes through on tracks like Child is the Father and I Love To Say Dada. But this kind of notion isn't unusual in art.
