Is there a valid reason to maintain military service exemptions for Olympic medalists?

Many people say they wish benefits like the Asian Games medals would be abolished immediately, but that the Olympic benefits should be maintained.
However, is there a justifiable reason for the military service exemption for Olympic medalists?
I honestly don't understand what benefit the nation gains when athletes like Yun Sung-bin win gold medals.
I'm not sure how it actually enhances national prestige either.
Even combining popular and unpopular sports, it doesn't seem like it would even come close to the influence of BTS.
I feel like winning a Nobel Prize, hitting No. 1 on Billboard, or being the head of the world's most valuable company would be more appropriate for enhancing national prestige than an Olympic gold medal—though I know that's unrealistic considering their age groups.
I assume it is being maintained due to the various vested interests within the sports community,
but from the perspective of an ordinary citizen, I don't understand giving military benefits to Olympians.
Even if I make a huge concession, I think it would be acceptable to require them to fulfill other military duties, such as serving as public service agents, after their athletic prime.
