It was just a few hours ago that someon on this site ask if Obama could become a dictator and now we get this executive order. Note that it was signed on Friday but only released late on Sunday.
Reading through this I can see where the authority for "national security and defense" needs is completely under White House control through the National Security Committee (all cabinet officials), the Homeland Security Agency, and the National Economic Council (section 104). This gives them control of resources (material, water, industrial, transportation) over the needs or wants of the private owners (section 801, A).
To put it plainly the White House is giving itself the authority to control constuction materials, transportation, water resources, food resources, industry in the event of a national security crisis which has not been defined. It is up to the POTUS to determine what a national security crisis is. The stage has been set.
