What I'm wondering is: can't Facebook create intent? If they know my favorite bands and location, can't they sell me concert tickets I might be interested in?

What I'm wondering is: can't Facebook create intent? If they know my favorite bands and location, can't they sell me concert tickets I might be interested in? If they know I'm in school and who my friends are, can't they not only advertise new places to rent, but who I can rent with depending on similar interests? It seems like they have all the information they need to create intent, they just need to develop that "Oh, I got that through Facebook" reputation.
