the reason that property is so expensive is because that's where the people are. There's no point in avoiding the biggest cost of air freight - getting goods to consumers who don't live near the limited freight hubs, if you land it in the middle of nowhere and now need to ship by rail or truck AND last mile delivery
There are lots of people inland and away from sea ports. Many hubs of industry (such as Wisconsin which makes many mechanics' tools) could take advantage of this if it were available.
