also don't people name stars all the time? why is this a problem?
There are more stars visible from the planet Earth than you could imagine. If you take any tiny chunk of the sky you can see at night and use a high powered telescope so that that patch is the only thing you can see, you'll see even more stars you couldn't see before. If you select an even smaller patch of that piece, and use an appropriately higher powered scope to see only that bit, you'll see even MORE stars that you couldn't see before.
It's like naming a grain of sand. Nobody cares because there's so many of them that it doesn't matter.
Galaxies are completely different. Galaxies are huge discoveries and they're something of actual value. They're more than little specks of light in the sky, they're home to billions of stars, hundreds of planets, and an innumerable amount of space debris. They're unique and exciting to see.
