> Wouldn't be surprised if SpaceX just continues to launch such satellites causing unintentional interference, to then claim in case of escalation how uneconomic it will be for them to correct this issue now and how the financial impact to SpaceX needs to be valued higher than scientific needs.

At least Starlink satellites need to be replaced every few years anyway due to their low orbit. That is a natural ceiling for economical questions - ITU et al take years anyway until anything is actually enforceable, so SpaceX has ample time to prepare should there be a relevant movement in ITU.
