How are fundamental laws of physics set up in such a way that you get the same effect (correct me if I’m wrong) if you move with speed near C as well as if you stay near the event horizon?
To me, these two “activities” are different but yet time dilation (and space contraction) happens in both.

Who know? That’s what Einstein postulated to be true, and thus far had held up under every possible test.
The key reason for this postulate is the fact that gravity cause the *same* acceleration to *every* objects. That led Einstein to suggest that maybe gravity is an illusion: these “falling” objects are actually moving “straight” but we look at it from the wrong perspective. If we accelerate from a different object, from our perspective it’s the object itself that is accelerating. Once you accept that postulate, then acceleration is the same as being under the effect of gravity.
