why is there a “safe to eject” option for USB sticks?

Question

After you’ve transfered all your data on/off, why cant you simply take out the stick? where’s the harm?

ELI5 answer – your PC can finish writing the file to the USB stick, but inside of the USB stick the file might not be “finished” saving. If you pull the power, the USB stick might lose that file, and maybe even other files too.
