I've reviewed this and your other comments on the thread, and I think you're making a mistake, believing that to solve the loneliness epidemic, you primarily need to "reach people."

As long as leaving the house and making real contact is harder (requires more self discipline) than staying in and scrolling, all you can do is project a message to folks at home, like "hi, you're not alone in feeling lonely," but you haven't solved the fundamental problem: it's harder to do the right thing than it is to do the wrong thing.

To solve the loneliness epidemic, you have to make the right thing easier than the wrong thing. "Reaching out" to more people will not accomplish that. Elsewhere in this thread, you've rejected the idea of pursuing a public policy, but policy is the only answer anyone's provided in this thread that could make that happen.

(Now, it turns out that you'll have to do a lot of outreach to make a public policy happen, but you'll be asking for their vote, not a regular commitment to show up weekly at a club; outreach is the right approach to that problem.)
