  We suggest that a randomization of the pseudo-dipolar interaction in the
spin-orbit-generated low-energy Hamiltonian of YbMgGaO$_4$ due to an
inhomogeneous charge environment from a natural mixing of Mg$^{2+}$ and
Ga$^{3+}$ can give rise to orientational spin disorder and mimic a
spin-liquid-like state. In the absence of such quenched disorder, $1/S$ and
density matrix renormalization group calculations both show robust ordered
states for the physically relevant phases of the model. Our scenario is
consistent with the available experimental data and further experiments are
proposed to support it.
