Perhaps you forgot that for each cone you considered, there is a force due to an identical cone on the opposite side that cancels it. The net force is zero on average.
There may be some local fluctuations however, For example our Milky Way and the nearby Andromeda Galaxy will eventually collide in four billion years or so.
