As someone who organized two very large social groups on Meetup in NYC, let's delve into your suggestions a bit more.
> Pick a social hobby. Pick up sports, hiking / running / reading / trivia / sports groups.
It is very hard to pick up a new hobby as an adult.
By 30, most adults (in the US; earlier outside of the US) will have real full-time job responsibilities, a significant other and a few children. Since the children will be young and will need almost all of your time and attention, that leaves little time for anything else.
Families with access to parenting groups will likely be living in bigger cities with high-enough density to support that. This also assumes that you have enough free time/money to participate in these activities (unlikely if you just spent most of your free capital on the house that you just bought because houses are at an all-time high now...).
Many new families are living in HOA-run communities that are wholly designed to be traveled by car, in towns that are also designed to be traveled by car, because you'll likely be commuting to work and back...by car.
Taking your kids on a walk to the grocery store that's 15 minutes away and seeing lots of people on your path isn't possible in these towns. Instead, you're driving four minutes to a huge supermarket where you'll run into families who are also rushing to pick up their groceries because time is scarce, and then driving right back.
Can you interact with neighbors and enjoy community in this environment? Sure! If you like your two or four neighbors in your surrounding area, and if they aren't filthy renters like me who aren't in it for the short-term. (Rentals are also increasing...because houses are at an all-time high and life happens...)
If you're childfree and live in a large city, then, sure, tons of opportunities to make new friends. Unless you're a lawyer working 100+ hrs/week or a SWE grinding at a startup that just hit PMF and is hyperscaling. Or you suck at breaking through cliques. (Lots of people suck at this; myself included. Don't feel bad! Most people make most of their lifelong friends in grade school or church, as a youth, so most times, you're trying to shoehorn yourself into a group that has developed decades of direct and indirect ways of communicating and interacting with each other.).
> Take a class.
> Take up a cause - volunteer your time at the local farm, shelter, political office..
This is actually good advice, but, again, time is scarce for many people.
This is more or less like saying "wanna lose weight? just eat less!" Not invalid, but also not helpful and very dismissive of people needing different things.
> Kids don't go to school with the goal of making friends. The friends are a byproduct.
...of being in an enclosed environment with other humans for eight hours a day, doing things they might or might not want to do. Kind of like work actually...
Let's be clear. I'm not saying that it's impossible to make friends as an adult. I've done it, and I've met tons of people that have done it!
I'm just saying that it's significantly easier to make friends at work.
More importantly, it is a lot easier to foster a culture and a work community in the office.
