Do you think students should need a specific license to read a book? Do visitors to an art gallery need a specific license to look at paintings? Do audiences need specific licenses to watch a play?

Those people will be influenced by what they've read/seen/heard and their own future writing/drawing/filming/acting/editing/playing might draw inspiration from what they've learned, and they might incorporate things they've learned into their own future work.

Literally every book, song and work of art is "violating copyright" on the thousands of other works that the creator learned from while growing up, if we hold the same standard.
