Key distribution is already solved until someone can actually solve a large discrete logarithm problem with a quantum computer.

You cannot use this mechanism to send messages, only to agree on a secret that neither party chooses.

Even if someone can solve discrete log, we have other algorithms like kyber.

QKD also isn't safe against (active) MITM attacks, which is kind of important.
