I know your opininion is as valuable as mine and I know that there are assets in DXB, just the value will be difficult to predict. In an empty city the value of a powerplant is zero. Expected future drop in value will be taken into account.
It won't only be DW that can't get loans. Any company from the same owner will be marked contaminated and have major difficulties renewing loans. Anything related to estate in Dubai will have major problems obtaining/renewing a loan. Anything that doesn't represent a clear asset can be used for guaranteeing a loan. Again just my opinion.
