No, that's just not true. Privatizing a poor person's drinking water, as bad as that might be, is in no way similar to shooting that person. Privatization may be reversed, for one thing, and it may be transgressed as well -- the poor person can simply refuse to cooperate with the privatization scheme and steal the water, for an extreme example.  Laws don't have to be obeyed in the same way that bullets must be.  And even without contesting the matter, privatization may also be adapted to for survival, at the very least, in ways that bullets cannot be.
