macOS has SIP (System Integrity Protection) which can be disabled. Your mom would not disable it. No non-technical person i've ever met, even knows what SIP is, let alone has disabled it.

Security researchers, for example, can disable it. And use this to find security vulnerabilities.

The point is, as users we should have the ability... Apple (or any company) should not be allowed to dictate what people are & are not allowed to do on the devices they own.
