If it works for you then no!

But for me, I like using Plex or subsonic so that I can easily access my entire collection from my phone. I have my server setup with automated tooling to download new albums from artists I have monitored, torrent client is always on, I can search for and add music from my phone (as long as I connect to my VPN on the home network). All of this makes sense for my use case, especially considering that I already run the Plex server 24/7 so friends and family can stream whenever they want from it. None of it is on my desktop, so that the server doesn't grind to a halt when I'm gaming or visa-versa. Also I don't have to leave the gaming computer running all the time. And I have the server drives setup to pool their storage together, so adding new drives is relatively easy.

But obviously a setup like this doesn't make sense for everyone. I've spent way too much money on server equipment (mostly hard drives), but one could do a similar but scaled back version of this stuff with an SBC like the raspberry pi. As long as you have the time and will to get it setup.
