> what's the issue with just running LibreOffice on your computer
The key advantage to Google Docs, an otherwise ordinary if not fairly lightweight word processer, is the ease of sharing (even if only with yourself on multiple devices) and collaborating with others.
I've never heard of LibreOffice online, but depending how well it does those things, it might or might not be viable.
As a word processor alone, Google Docs is nothing special and LibreOffice probably has more features.
