Your post only really compares it to other languages for the purpose of saying “yes, it really is a language”. Not for deciding whether learning another language would be better than learning it.
I can’t weigh it up against every other opportunity available to you on your behalf.
I’m not expecting you to compare it to every single possibility, but it does take a lot of time, and that’s something you need to take into account—the opportunity cost is huge, and you’re really glossing over it. There are a lot of things you can do in four years other than learn ASL.
