How to control abuse, crime, etc. of citizen trading?
The same way you control abuse, crime, of stock trading. In short, you don’t unless on highly exceptional circumstances.
Who have the power to issue citizenship? Well, we can start with those that are in power in the first place. The people in democratic country. The sultan in monarchy.
