Apparently, that’s not enough. You will also need your own “app view” which means you will be self hosting an over engineered forge with social features you can’t use… so why go that road to begin with is beyond me tbh.
You CAN host your own Tangled AppView. You CAN host your own knot. You DO NOT have to in order to self host your own PDS. Each of these layers are decentralized from the other.
The appeal of bobbin is it's fully stateless and pretty lightweight. IIRC you can run all the infra to run a proper tangled appview (including bobbin) all on your average lower middle end general purpose cloud instance.
