In an ideal world, we wouldn’t have a tiered education system and that everyone will have access to master any subject/curriculum regardless of age. Therefore, we wouldn’t need an arbitrary and flawed aptitude tests.

The aptitude tests are more for matching folks who will be more closely matched in terms of quantity and speed of learning. There is definitely some virtue signaling as well via elite admissions, but that doesn’t exclude anyone from learning pretty much most subjects.
Maybe I don’t understand what you’re suggesting.
