  In a recent Letter, Nayak argued that slave partices are always confined in
gauge theories of strongly-correlated electron systems like the t-J model. The
argument mostly relies on Elitzur's theorem and the fact that the effective
gauge theory under discussion is at infinite coupling. On the other hand, in
the previous papers we studied dynamics of the gauge theory of the t-J model
showing that the slave particles are in the Coulomb phase below certain
critical temperature T{CSS} that depends on hole doping. We comment on the
discrepancy between the results in two papers.
