The problem is with the change and transition, not the fact that solar time doesn't inherently match wallclock time.
Even the actual position statement doesn't have a strong argument for which one should be the permanent time, and is worded as a hunch:
> Although chronic effects of remaining in daylight saving time year-round have not been well studied, daylight saving time is less aligned with human circadian biology — which ... could result in circadian misalignment
