No, we can not do better but we can speculate - if you prefer that word - as to the reason why this was implemented. It is reminiscent of the abundance of prompts in earlier iterations of Windows which made it the subject of jokes like these:
You moved your mouse,
are you sure you want to move the pointer?
[OK] [CANCEL]
It is hard to fathom why Apple - which prides itself on being user-friendly - would go in a similar direction. Absent inside information all we can do is speculate (or 'guess') as to their reasoning. Unless you have inside information it is hard to do more than guessing why they implemented this user-hostile prompt. There is no similar prompt when you disable WiFi even though that can cost the user money.
User hostile? It’s a warning so people don’t get locked out if they don’t have a wired keyboard. Disabling WiFi doesn’t keep someone from using a computer.
The user hostility lies in the fact that this warning shows up each and every time without the option to keep it from appearing for those who e.g. use USB keyboards.
