Since light particles travel at the speed of light, we know it's possible for something to travel at that speed. However, since all things are relative, and if time does stop at the speed of light, then we can not measure the velocity in conventional terms. Consider from the perspective of the light particle, how long does it take to travel a "light year"? If time stops at the speed of light, then how can we rationalize the definition of a "light year"? There is no time from the perspective of the light particle. So, why would not it be transported instantaneously?
