I already am self hosting everything. I have an 8TB drive over half full at the moment, and filling up fast now that I have a 4K TV. I also have an Openvpn server so that I can access my content when I’m away. I’ve had this setup since before torrents were even a thing.
It’s only select movies that I’m getting in 4K, and any Star Trek that comes out in 4K or maybe the Star Wars 4K77 fan edit that was just released. But even then, they add up fast. I can barely tell the difference, but for some stuff I just want the best available.
Edit: I also did this when 720p VS 1080p was a thing. For a vast majority of stuff, 720p is fine and I’m not going to update that stuff. Most stuff released today isn’t even available or 720p anymore, so I’ve defaulted to 1080p for most new stuff.
