A scenario for achieving a low velocity dispersion for the galaxy [KKS2000]04 (aka NGC 1052-DF2) and similar galaxies is presented.  A progenitor halo corresponding to a $z=0$ halo of mass $\sim 5\times10^{10}\; \textrm{M}_\odot$ and a low concentration parameter (but consistentwith cosmological simulations) infalls onto a Milky Way-size host at earlytimes. {Substantial removal of cold gas} from the inner regions by supernovafeedback and ram pressure, assisted by tidal stripping of the dark matter inthe outer regions, leads to a substantial reduction of the velocity dispersionof stars within one effective radius. In this framework, the observed stellarcontent of [KKS 2000]04 is associated with a progenitor mass close to thatinferred from the global stellar-to-halo-mass ratio. As far as the implicationsof kinematics are concerned, even if at a $\sim 20 $ Mpc distance, it is arguedthat [KKS 2000]04 is no more peculiar than numerous early type galaxies withseemingly little total dark-matter content.
