I'm excited by the prospect of Online marketplaces. I think an interesting area of discussion though is that many of the examples you highlight around inefficient use (garaged cars etc) are a result of wealth creation. Prior to surplus's created via wealth creation it was not really viable to exclusively own so many things. Thus - like fat royalty - these things almost became a status symbol. That's why I find AirBNB so fascinating. People are willing to share idle space in their home.
