A failed attempt is still an attempt. Therefore your "because" is wrong.
SR is an attempt to describe the world. Later it was found out that the
world is different but that does not affect what SR is.

No, it is not. SR is about the geometry of the world, not about its matter
content except that the matter content must be compatible with the geometry.

 SR is first and foremost an attempt to explain the Michelson-Morley experiment.
 The calculation shows that, according to the experiment, w=v+c=c
 Which is absurd.

 No, it's not absurd.
 You need to think in terms of physical reality and ask yourself the question: why?
 Or: Why doesn't the speed of light depend on the velocity of the source?
 The reason must be: because speed of light isn't controlled by the source, but by the space inbetween source and receiver.
 This is an obvious requirement, anyhow, because if you would give it up, than all sorts of strange effect could emerge, which we do not observe.
 E.g.
 if the space itself would not controll the speed of light, than light could have different velocities in the wastness of the universe.
 Now, already a miniscule different velocity of light rays would add up to large discrepancies in the time of arival at a remote spote, where an observer would like to observe them.
 Since everything moves in the universe, we would encounter 'blur' effects, if light would not always maintain the same speed, because we could see rays originating from the same spot at different times.
 This would look, as if the e.g. star 'smeared out' and had a strange halo or similar, because the solar system moves and the entire galaxy rotates.

The general law of addition of observable speeds, I gave it here.

It is also the same law as that used by relativistic physicists, but written a little differently, the results being obviously equivalent.

We notice that the speeds do not add up in a Newtonian way, but in a relativistic way, and that nothing, whatever we do, can exceed c.
The question that arises is: "Why did we arrive at this strange equation?"
We can only understand it if we KNOW that the speed of light is an anisochronous decoy, while in principle the electromagnetic transaction is instantaneous.
It becomes obvious that a decoy added to a decoy is not going to facilitate the fact that 0.2c+0.4c will make 0.6c.
It is as simple as that.
