If someone believes that they have nothing to gain from interacting with a group then who are you to tell them that they should do it anyways for growth? You could make the same exact argument about any form of interaction. Don't want to interact with the node.js ecosystem? Why not? You will learn so much and grow as a person. Will I? Really? How about a book on group theory? Sure I will probably learn something, will it be useful? maybe, more so than the class I already took on it in college? who knows, certainly not you more than me.
Also the idea that people just want to sit in front of the TV and not learn anything new or grow is completely insane and usually only comes up when they aren't learning the thing that you want them to know. If it appears like that it's only because they are stuck in some system, much like the one you propose, that wants them to learn unactionable knowledge
What is the Appearance of Interaction? Just because it's very obvious that you are interacting with some group doesn't mean that you interact with that group more than some other group that you don't know about. If you go to a new website your browser runs some interesting scripts, much like a TV show this attracts your attention, eventually you decide JavaScript is important and you should learn about it. You have entered the JavaScript fandom, it doesn't matter to you if gravity acts on you constantly or a krebs cycle complete in your body (~10)^~21 times a second, JS is clearly more useful to know about, right?
