Yes, in a way your philosophy of seeing things is correct, but remember that in the past, ORBX had already supplied countries like Germany, Ireland, Norway or Scotland for FSX and P3D! So in my opinion, and this despite I also appreciate the landscapes of the United States, it would be better in the first place, to see developed in TE these for AFS2. But the path is still very far from reality.
Landclass regions are much cheaper to develop because land use data is often freely available by local governments. If sales are lower than expected it's not that much of a problem. Orthophotos are usually quite expensive. In Germany, AFAIK only two federal states and three cities offer free orthophotos. According to a post by developer Christian Bahr Orthophotos for all of Germany provided by government sources cost 36000 Euros alone plus development costs for the scenery. You'll have to sell a lot of copies to make that profitable.
