The time when many are most likely to create a new idea, that should be profitable to originator of the Idea, is when they are University age. After they graduate they will be required to sign a Statement to sign over all their Patent, Ideological property rights.
I suggest when they are at a University age, they protect their future Ideological Property Rights, from being stolen from them by other students or by corporate espionage, they use Qubes. After one signs the statement, the individual will need to follow the law.
