Why does lag compensation exist at all? Can't players just aim for where the enemy is now?

At 80ms latency, the enemy moves ~1 meter ahead during your shot's round trip. If servers only tested hits against present-time positions, laggy players would have to aim into empty space to hit stationary enemies — making the game unplayable for anyone not on fiber. Lag compensation tests the hit against where the enemy WAS when you fired, giving everyone fair aim.
