I don’t think you know what legally binding means. By your definition laws are also not legally binding because they can’t make you do anything; they can only tell you what will happen if you break them.
You’re right in that no contractual obligation can override your rights (and their obligations). Nevertheless the breadth of the things to which you can give consent to (often unknowingly) is wild.





I think this is the one time I can pull out my fancy word knowledge and say: this is a non sequitur.
Also my original comment intended to point out the flaw in the above commenters argument (which argued that you can sue games companies that sell you digital games and then revoke licenses).
Other than that, I agree with you.
