>A box full of helium where exactly half of the helium is on one side and half is on the other is not appreciably more likely than one where there are 17 more helium atoms on one side the box than on the other despite requiring less bits to describe. Plus, how does one decide which information is counted ("which of two distinct volumes the atoms occupy") and which information is not ("full position & velocity of every particle constrained only by uncertainty")? Because if we don't make that [artificial] distinction, each box has exactly the same amount of information.
