Totally agree, i just dont get it at all, then again i dont do "networking" in real life either, i'm just not wired like that at all. I find that whole ecosystem of networking, sharing contacts, phoning people to "touch base" very fake, incestuous and pretty sleazy, so i just dont take part in it at all.
I know though that people who are good at it can be extremely successful business people because they know how to work the system, its definitely a flaw of mine, but its not one i want to correct because of my general distaste for how its done. Luckily, i do ok on my own path.
