Great question - the fundamental entry point of the air traffic system is this VHF control audio. Everything is downstream of that. Trajectory planning misses the intention signal on the frontend.
The example in the original post is actually a good case study for why trajectory planning alone breaks down. By the time the aircraft are on a predictable collision course with each other, you've lost 10+ seconds of potential remediation time that you would've had if you detected the error when it was spoken. Those 10 seconds really matter in our airspace.
