If you work completely remotely that's fine, but at least the article was saying more that millennial were moving to these places because the existing demand for workers was there, especially knowledge workers, and that's just not really true here unless you want to work at the headquarters for a giant insurance company.
The scope of the article is generally true, I was just surprised to see my hometown included, is all. If you're just looking for cheap places to live and work completely remotely, there are tons of other towns nearby that are much cheaper. Hell, just go 20 miles outside of Bloomington and you can get a house at about half the price that you would in Bloomington, in much smaller towns. I have old high school buddies that do exactly that.
