Let me guess.
The clients you are talking about probably are not national entities, especially non central governmental entities.
Since the entities we are talking about are non mainstream business in our society, they may not be the service target of our national finance infrastructure.
Capital is still a rare resource for our economy.
What's more it can play a role of controlling tool.
The fundamental criterion is property right.
Because we aren't legally entitled with the upper right,
there is no motivation to stimulate private business with fund from mainstream financial institutions.
I am not sure, but I hope my guess is reasonable.
Thank you buddy.
