I have to be contrarian here. If the people are US citizens and are not linked to any terrorist groups, and are obeying the current laws regarding zoning then they have every right to build/rent or buy property as any other citizen does. Presumably someone sold them the space.
No right is being questioned; propriety is being questioned.
