I still disagree with and believe it’s based on purpose. Speaking for myself, I, as a human being, as a sentient life-form (to highlight where I believe these rights are rooted), will not be denied what I perceive is my right to deconstruct and understand the universe before me. Nothing in all of creation is sacrosanct. If I’m not using your product for monetary gain, and nobody buys it, and it has no impact on the value of your property, well then… you have no business telling me what I can or can’t do with it… ‘you’ being the companies that is. 
My example of the bungee jumping company shows is an erroneous belief. You can not (in my country at least), in ignorance, sign away rights guaranteed you by your country. To be more clear, company agreements of any kind do not supplant established laws.
