"what's a network, how is it different from the internet, and why do i need to add a device to it?" many people don't understand the implications of vpn'ing into their home devices. being able to access their network shares "over the internet" in a safe way. being able to access all of their random self hosted stuff without needing to be at home without needing a reverse proxy. all the while being easier to secure and safer than internet facing alternatives. these are things that people will actually understand that aren't just arbitrary abstract ideas.
