There are about 0.0015 BTC per human being on this planet at this time. Therefore, by buying 1 BTC you are depriving 666 human beings from owning their fair share of bitcoins. Evilness of those who hoard thousands of BTC is simply despicable. Mu-ha-ha.
In all seriousness I have actually thought of this as a model to value BTCessentially, if every one needs 1 BTC, is worth that multiplier of people. so 1BTC = the net worth of say 500 people. However it has to be the average 500 people and so not that high, say 1000K each given you are including children, economically deprived countries, but also some of te 5% ultra rich are in there.
so 1 BTC = 500 * 1000
gives 500K per BTC
but you have to divide this by market penetration, which is say 5% 25K
this may give a order of magnitude either way to say, 2.5 K to 250K is reasonable per BTC, to put absolute limits on BTC value
to be one of the 21 million...feels good.

MWAHAhahahaa ... oh.
