Would it be possible to calculate the maximum theoretical value of bitcoins by dividing the world gdp by the maximum number of bitcoins, if so then i am going to have the best retirement ever! 
if we say the world gdp is $80 trillion (its rising so this will cover future estimates) and knowing that the maximum number of bitcoins is 21 million then we have something like $4 000 000 per bitcoin.
I am sure this number is wrong and makes some massive assumptions but if we were to find a theoretical maximum value how would be go about it, is it possible? I mean in the context of when/if the world moves to bitcoin
EDIT:
Someone asked about the total cash in the world and a very nice person gave calculations and explanations leading to a value of $46 trillion which was around the same as the GDP at the time so it seems that GDP may be an adequate estimate for the amount of money in the world. Either way, with a total amount of cash at $40 trillion we would still get $2 000 000 a bitcoin
