Something being a wave does not require a finite velocity and in fact there is nothing in physics inconsistent with an instantaneous velocity of light. We know that the two-way speed of light is finite, but all currently known laws of physics are consistent with an instantaneous one-way speed of light [1]: https://en.wikipedia.org/wiki/One-way_speed_of_light https://en.wikipedia.org/wiki/One-way_speed_of_light I am not suggesting that light is instantaneous, only that there is nothing inconsistent with it being so, and that consequently trying to reason about these matters on the basis of what appeals to our intuitions is not sufficient to come to any solid understanding of this phenomenon.
