> If unauthorized copying is akin to preventing a potential sale then using a gym for an authorized/non paid amount of time to try the gym without paying is not stealing.

Well using a gym for free isn’t stealing either. Although the analogy is flawed because a gym has a limited capacity so you could take up the space of legitimate customers, which you don’t do when torrenting copyrighted stuff.

> Creator of the thing sets the terms. People have the ability to not buy it if they do not like the terms. But they do not have the right to alter the terms via stealing.

No, creators can’t just redefine words. It’s not stealing, because you’re not taking something away from someone.
