But it probably actually *is* realistic. We're just not accustomed
to thinking about the pressure of only a few tens of thousands of
molecules. It helps to realise the 'balance' between pressure and
density of a condensed phase system (e.g. any watery system). If the
density is only slightly off, say 0.1%, pressure will be way off,
say maybe a factor of 100, due to the intrisic low compressibility
of the medium.
