The interesting thing that I didn't catch the first time I read the EO, is that it's RECURSIVE!
The order allows all property and interests to be seized from A) Anyone determined by the Treasury Secretary to be guilty of corruption (among others), and B) anyone who assisted someone determined in 'A)', + anyone who is BLOCKED by this order. As those in section B) are also considered to have been BLOCKED, anyone who assists them will also be determined to be in category 'B)', and will thus also be BLOCKED.
This extends to the extent of material support for those who committed or assisted in the offenses listed - IT DRAINS THE SWAMP!!
