I think the experiment is fun but the principle is flawed imho. At best the method will find the average _utility_ value of fb for the study population. Another commenter remarks that it would be ok to pay 1k to access fb if there is a promise of value (ie the "network" is still there) but projects that if fb became a paid service, that most users would leave it so the risk of losing utility value from fb would not be anywhere near 1k.
