Yes. All human intellectual work comes down to discovering a really big number. This labor has immense value. The data itself can be trivially copied and distributed worldwide at essentially zero cost.
Society needs to find new ways to value this human intellectual labor. New ways that don't depend on forcing artificial scarcity on the result.

Helpful to whom? To the monopolists, sure. Meanwhile everybody else has been robbed of their fair use and public domain rights.
> enforcing copyright in the 21st century helps us to protect our computing freedom
Absolutely not. The number one reason why computers are no longer under our control is copyright. It is impossible to stop copyright infringement if we can create and run whatever software we want. They must have mechanisms that stop us from running unapproved software in order to have any hope of enforcing anything. Otherwise it's trivial for computers to share data with each other, it's as natural as a river flowing.
