I'm ambivalent about growth with a lean towards "NGU of random adoption" probably doesn't do anything positive for me. I don't care how many people on earth send emails to each other; I care if I can email with a small set of very specific individuals, on our own terms.
It's the same with nostr.
"growth for growth's sake" is a marketer or VC's money-multiplier game and I think it's an antipattern.
"Organic, lumpy and specific growth in specific communities driven by emergent market phenomena with that community" is a different story entirely, and likely not something a 3rd party is going to make money off of.
I want growth because is exciting to build things and make them grow. Stagnation is lame.
I also care about meeting random people and connecting on nostr instead of some centralized platform.
