you're partly right - the only resolution here would be to disable javascript, which makes a great part of panopticlick work (identifying installed fonts, etc.). however I think this kind of user recognition would be an overkill for a site with so many impressions like facebook - the computational effort to assign an account to each set of features must be huge (thou maybe sometime later ... when privacy laws get more restrictive).
