It is shown that the isotropic dispersion relation, line shape of the spectral function, and remnant Fermi surface found in recent photoemission experiment in insulating Ca2CuO2Cl2 by Ronning et al.(Science, 282, 2067 (1998)) can be consistently explained by a direct holon hopping process which fundamentally undermines the conventional self-consistent Born approximation approach to the t-J model.
