Tho that only works up to a certain scale, after a while you reach saturation and then there's nothing left to dilute into. Really no different to carbon emissions: For the longest time we thought we could just "dilute" these emissions into our atmosphere, decades later we have come to the realization that even the planets atmosphere ain't infinite and thus can be saturated by human activity.
