Everything that has played out to giving Bitcoin the edge it has at this moment deserves the attention and recognition they are getting and although 16BTC with the current fiat value seems abit high, it's still relatively okay to value such an historical piece that played a unique role in bringing Bitcoin to the limelight with such worth.  If satoshis white paper wasn't a popular resource that's in the public domain, it's most likely that it would have gotten similar worth as Albert Einstein note. At the end of the day, it's just a matter of contextual contribution to humanity, and when Bitcoin eventually gets the kind of public acceptance that Einstein works has from the globe, then pieces as this will go a long way to becoming of a higher worth far above what we're currently evaluating it now.
