a healthy economy is a chain of different segments....How about sustaining only with the wealthy segment who still depend on others for 90% of their reqs starting from business, household, trade, shopping and even necessities! And its too early for Doha to say they want only wealthy class... the outskirts of the city looks much worse than the most rural villages in Asia. If there are robots to all of the jobs ya lets dream of that! So putting a total restriction on something when its mismanaged is the most stupid thing to do. What if entire world bans Gas then and imagine the deficit on Qatar's export.
