There's lots of reasons I don't want to set this up

The point is that you now have another app to manage or learn about just for remote viewing, and the general public can't and won't manage something like that. People like us, no problem, its easy, but my dad would never be able to, for example. He can install plex and just log in to an app anywhere to use it though.

Also, dont forget that many households have non-static IP addresses, so now you need more management for that issue (again, easy for us).

You do then still have to expose JF to the open internet. That's not without risk. Neither is Plex but they do make it a point to secure all their endpoints before login.
