Fine. I'll rephrase it for you.
Photons are instantaneous. They travel at "light speed" not because that is the limit of how fast a photon can travel due to it's own properties, but because that is the limit of how fast a particle can travel through space-time.
Imagine if you had a car on a race track. The car can travel at any speed. But the race track has a speed limit of 100mph and it's physically impossible for the car (or anything else) to travel faster than that speed limit. If the speed limit were higher, the car could go faster. If the speed limit were lower, the car would have to go slower. The "speed limit" of the car is not changing, the "speed limit" of the race track is changing.
Light does not have a speed, the Universe does, and light is forced to travel at that speed.
