The reason that pay transparency laws (which probably don't apply to this position, but exist in other states) require salary ranges and not a specific number is precisely to account for the fact that different applicants with different levels of qualification may merit different compensation in the same role based on the impact they can have. So "depends on the qualifications of the individual applicant" is kind of besides the point; a wide range can account for that.
"I'm not the King of Hiring" is fair though, if you're in a jurisdiction where there is no transparency law and you're not setting policy for your company, you may well be required not to provide this information publicly and that's just how it is.
