The article includes thoughtful examples of declining information asymmetry (buyers and sellers have different knowledge) and new methods for operating markets that have symmetric information.
The conclusion makes a heroic leap to tie this all to market regulation. I don't quite see the logic tying the examples to that suggestion, but I like the rest of the article.
