without our society of sharing resources, ideas, and science where would we be?
reselling these ideas or resources in a "commercial" way without the creators permission is already illegal.

The more often your work is shared, seen, admired, learnt from the more chance people will value it and pay for the product commercially.

If sharing is natural and 99% of young people are doing it please do not consider restrictive laws that will have the effect of the extreme minority controlling the majority, its a recipe for disaster politically and financially.
