Laying fiber is expensive and time consuming.

Satellite is - once you've got the infra up in the air - very straightforward, with the downside that your satellite ISP is likely owned/operated by an unregulated billionaire nutcase that will turn off your access if he doesn't like you any more (c.f. Ukraine front line). It's hard to do that with regulated fiber backhaul, but not impossible.

I've seen a few wireless ISPs mentioned here before, which can be a nice hub/spoke model - run fast fiber to a community, but distribute via wireless (note, not WiFi) to homes and businesses within range.

I'd definitely love to see more community-run ISPs in the World, it's how the Internet should work, really.
