Understandable. Sadly, you can't exactly set up an off-site backup in your living room, no matter how much you want to.
When someone doesn't want self hosted NAS, it feels like they often just dn't want to bother with it. While I haven't used them myself, I've heard good things about ready made NAS boxes.
For self built, it has been too hassle free in my experience. I want to tinker more with the NAS part, but it is just too reliable & maintenance free!
While I know that they're different, the more common reasons for not wanting a NAS just remind me a bit of some "reasons" to not care about digital privacy or security.
