At my previous job, I had a coworker who was hired on after the office decided work from home would be permanent. Everyone in the office was originally from northern Illinois since that’s where the office was, but she lived in rural Iowa in a farm with her husband. She mentioned how she really wasn’t able to get a job like this previously as she would have to commute long distance to the city. And of course she and her husband can’t just pack up the farm and move it closer to her work. So you’re absolutely right! Work from home could very well be the thing that saves small communities that have been largely going off.
