I think you might have heard a similar statement in 1991 to the effect of:

"It doesn't take economics into consideration. most people/companies aren't that interested in sharing their documents in an anonymous way.

WWW is a web of documents. SemWeb is a graph of data.

You have a good point, but we're not using the web today in the document oriented way of the early 90's. Sure, if someone will invent a way to use the semantic data in a way that could generate income or market value for the data owner/publisher, then the SemWeb will take off. However in the current presented form, I don't see a strong incentive for any profit oriented agent to just put out their data in this way.
