There kind of is a similar setting on NEW macs, but using my example, most people don't have new macs, even if they do have new iPhones, so they're not accustomed to these features.
Also, apps have the ability to move you out of the app, into settings and the screen where they want you to give consent. Some apps may not even function without this consent, even if they don't need it.
That's where the problem lies. Apps asking for control they actually don't need, so they can use it for nefarious purposes, without oversight.
