I guess it depends on the place, honestly. The best communities I've been a part of -- in my short existence -- revolved around bookstores. Maybe that's subjective, but I can also argue that Signal, WhatsApp, etc aren't the only viable community centers.

Also, I'm from rural US, and those places do revolve around churches, but the pockets of enlightenment revolve around bookstores. IMO, a healthy community has a strong group of intellectuals. Intellectuals tend to gravitate to bookstores.

And yes, you can definitely blame Amazon for putting bookstores out of business. I'm too lazy to find stats to support that, but there is definitely evidence that Amazon is to blame.

And sure, libraries are for the community's benefit in an ideal world, but I'm talking about the real world.
