"Congress shall have the power to... promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries;..."

which argument best supports this power of congress?

One argument that supports this power of Congress is that providing authors and inventors with exclusive rights to their works and discoveries incentivizes creativity and innovation. By granting individuals the ability to profit from their creations and inventions, it encourages them to continue developing new ideas and sharing their knowledge with the public. This, in turn, leads to advancements in science and technology that benefit society as a whole.
