Not weird at all. All my data is shared from a single VM but I access it from several others than run jellyfin and the *arrs, and a few other things. When you don't want everything running on the same virtual machine, you need to share the data over the network, even if it's all on the same physical box.

If you want multiple containers or VMs to have access to the data it needs to be shared from somewhere. As others have mentioned you can setup a VM to run a NAS OS like FreeNAS or just run a container with samba and pass the drive through to the container. The difference is how you access the data from the other containers and VMs. You'll access them via samba shares as opposed to local drives.

To my knowledge two containers/VMs cannot share the same physical or virtual disks in Proxmox. I tried and had to go a different route to get what I needed.

I feel like the average person doesn't need a computer most of the time. Anyone who's a "power user", for lack of a better term, probably does. I run a VM with a desktop OS on my Proxmox setup that I remote into from my phone for things that I require a full OS for but don't want to break out my laptop. I often find myself remoting into it from my laptop anyway just for continuity.
