It's not really for a purpose, its just what we observe to happen in the universe. Same idea as what is the purpose of gravity. We don't know why it is there and happens the way it does, but we can observe and try to explain it.
Dunno. I doubt anyone really knows. We can tell you what causes that limit, the overwhelming relativistic inertia of massive things as they approach light speed, but we can't really tell you why that happens.
Nor can we tell you why space and time adapt to keep the speed of light always at that speed no matter what. All we can say is that it does. And we have observational evidence to support that assertion. And we have some theories to show what happens to keep light at C no matter what. But nothing to say why.
Answering why has always been a weak point in physics.
The truth is that we have no clue why the 20 or so so-called natural constants that make up our universe are those values and not some other values. The speed of light is one such natural constant. Planck's Constant is another one. And the universal gravity constant is yet another.
When why is addressed, some of us start to get into the realm of philosophy. The anthropic principle of physics, for example, is the belief that the natural constants were selected so that life could evolve in this universe. There is no way to prove that; so it's strictly faith based like philosophy or religion is.
