Not true in M2TW. You can build anywhere which is not adjacent to another unit/agent that is not of your faction, inside your own region, not affected by any announced/unannounced disaster, next to another fort/watchtower.

You may think of point v when point iv occured, as you wouldn't know if iv occured or not until you realize you can't build anywhere within that region.
