Udev and systemd to merge

The Linux way of electricity networking does exist in your 2nd electrical example, its called a Widow-maker or other similarly ominous names. (for good reason)

s/Linux/Windows/

Widow-maker is used to attach to the upstream, to “WAN” power grid (this is what you “naturally expect” for some reason). This is Windows way.

In Linux you share your wall outlets (you local in-house “LAN” electric network) instead.

the entire concept of LAN vs. WAN only propagates this confusion

Why? WAN == WIDE area network (think city-level or even wider electrical network), LAN == LOCAL area network (think you own tiny in-house network with dozen or two plugs and few appliances). If you want to share electricity with someone you most definitely will do it using your local network (unless you have some serious reasons to use thing which is called Widow-maker or other similarly ominous names).
