Its not irrelevant, it means there may be more people out there who would love to be here but simply have not discovered it yet. And I'd say that can be a substantial group of new users. Especially users who may find their current platform fine but would jump ship if censored. Take Twitter for example, twitter in foreign languages can be less censored due to lack of moderators. So dutch people have not adopted Nostr at all even if they care about free speech because to them Twitter genuinely is the free speech platform at the moment. But yes, Nostr needs to exist and get more adoption (And prepare against the spam waves new adoption will attract). Its one of the few long term solutions against the ever increasing censorship.
