Agreed, but I'd say the likelihood of something in space disrupting an optical path between two satellites for any significant duration is quite small, much smaller than the potential for a cable to be physically damaged. But I'm still quite certain that satellites nor free-space optics will not be coming anywhere near the capacity of fiber in the foreseeable future.
