Why can’t I manage or disable “Ask to Buy” without owning another Apple device?

I’m struggling to understand why Apple’s setup process allows this situation:

I purchased an iPhone for my child and set it up under a child account, as required by Apple. During setup, I was prompted (by default) to enable the Ask to Buy feature so that I could approve any app or purchase requests.

However, I don’t personally own an iPhone or any other Apple device. I’ve since discovered that this means I cannot receive or manage these purchase requests, and there’s no way to disable Ask to Buy without using another Apple device.

Apple Support confirmed that the only options are:

• Find someone with an Apple device and sign in on theirs to disable the feature, or
• Travel to the nearest Apple Store to use one of their devices — which is not practical for those living far away.

Can someone please explain why this is considered an acceptable consumer policy?

Why isn’t there a web-based option or another way for parents without Apple devices to manage or disable Ask to Buy?

This feels like a major oversight in accessibility and usability for families who want to manage their children’s devices responsibly without being locked into owning additional Apple hardware.
