The way I understand it, you're citing an extremely theoretical
minimum, in the same way that one can point out that we're a long way
from maximum entropy in a flash memory chip, so it ought to be
possible to pack a lot more data onto a USB stick. The laws of physics
tend to put boundaries that are ridiculously far from where we
actually work - I think most roads have speed limits that run a fairly
long way short of c.
