> Policeman demands a bribe to avoid having a record on your license for driving

The policemen in my city were very specific about getting the fine digitally. They wouldn't handle cash even if it was for the fine.

> The answer to bribery is to take away the power from the government

A much more practical way would be to disassociate the approver and applicant. Eg: You can't bribe your University examiners Cuz they won't even know how to find your paper from lot.
