Share music between iTunes and Apple TV without subscribing to Apple Music or iTunes Match?

I just want to be able to listen to my iTunes (12.8) library from my Apple TV (OS 15.4) without having to pay for any subscriptions (Apple Music or iTunes Match). I can connect to my iTunes library on my other Mac with home sharing, why can't I do this with the Apple TV, they're all on the same network, even using the same Apple ID.

I feel like things like this used to be so much easier, now everything requires a subscription and/or uploading everything to the cloud. I've paid enough for the music itself, why do I need to pay to share it with myself! Ugh. Sorry this is frustrating!
