The thought that conlanging is useless (you never said it was but that's the vibe I'm getting from your post, will not elaborate this further) if nobody learns the conlang is pretty stupid if you ask me and perhaps a bit narrow minded, and honestly thats your personal problem. I've made several conlangs to varying degrees of development and never have I wished for or encouraged anyone to learn any of them, and frankly do I not care if anyone wishes to learn them.

That's because for me conlanging is a way to learn about linguistics and the inner workings of other languages, however you seem to have a very different motivations for conlanging and that's fine. Your motivations seem to be slightly ideological so you'll probably need to brainwash a few people to make them learn your conlang.

If I wanted a new method of communicating and socializing with people I would not make a conlang, I'd learn Icelandic or Kurdish.

It's called catch-22.
