That’s the thing, that’s NOT the only use for the platform. If it were, it wouldn’t be the best selling rifle in the US.

The primary reason for choosing one is weight.
My grandfathers Remington 721 weighs 8.4 pounds (3.8kg), carries 4 rounds, and in .30-06 is arguably a stronger caliber than the .223 in an AR platform.
My Henry .45-70, the caliber rated for all big game in North America (and jokingly rated by Marlin for T-Rex), weighs 8.1 pounds (3.67kg) and carries 4+1 rounds.
Something like the Ruger AR556 weighs a relatively svelte 6.5 pounds (2.95kg) and comes stock with a 30 round capacity, making it easier to carry.
I know, I know, 1.9 pounds (0.86kg) doesn’t SOUND like a lot, but it FEELS a lot heavier when you’re marching around the woods with a rifle strap digging into your shoulder.
And being able to pick up something fast and use it in a home defense situation makes all the difference in the world.
And make no mistake about it, the Supreme Court has ruled over and over that the primary reason for the 2nd Amendment is self defense.

“Private citizens have the right under the Second Amendment to possess an ordinary type of weapon and use it for lawful, historically established situations such as self-defense in a home, even when there is no relationship to a local militia.”

“The Due Process Clause of the Fourteenth Amendment extends the Second Amendment’s right to keep and bear arms to the states, at least for traditional, lawful purposes such as self-defense.”

“the Second Amendment extends, prima facie, to all instruments that constitute bearable arms, even those that were not in existence at the time of the founding,”

the "constitutional right to bear arms in public for self-defense is not a second-class right, subject to an entirely different body of rules than the other Bill of Rights guarantees.” The exercise of other constitutional rights does not require individuals to demonstrate to government officers some special need.
A huge comment, but I fail to find what you consider other uses beside what you commented on.
You don’t require any other use besides the desire for self defense. That’s the position of the Supreme Court.
The supreme court says whatever the fuck they want. It’s not some sacred institution that should be respected.
