We show that the statistical multifragmentation model with the standard parameterization of the free volume predicts a constant pressure as density approaches the normal nuclear density. This is contrary to the Raduta&Raduta result obtained by disregarding the center of mass constraint. It is demonstrated that in finite nuclear systems the partitions with small number of fragments play an important role.
