Your continual references to the universe as an entity keeping track and calculating things is extremely misleading for a layman reader. In particular, "one wonders how and where the universe keeps track of all these states" is completely inaccurate, for not only is the universe not a thing which keeps track of anything, but even if it was, any measurement of a continuous observable such as position or momentum has an infinite number of possibilities, obviously far greater than the finite 2^3000 possibilities you talk about.
Also, I should note that the choice of a base of two is rather arbitrary, as atoms are generally more complicated than dual discrete states such as electron spin, and the possible eigenstates they could collapse into varies wildly depending on what we are observing.
