I suppose that's part of the problem though, we are conditioned to value things based on the 'price', be that physical effort or numerical loss of 'money'.
It's only partly corporatism that is to blame for that, the main factor, in my opinion, is human nature. We love to value things by how much it 'hurt' us to obtain it. Sometimes, that is perfectly understandable, family heirlooms 'hurt' as in they are a reminder of those who have gone and can never return, Privacy is a very difficult thing to deal with as well, if someone walked into your house and stole something, does it matter if you can replace it for free? Maybe, maybe not, but the invasion of Privacy is a thing that cannot be easily defined from the viewpoint of ownership.
We've had the concept of 'Right of Ownership' since we sat in trees and screamed at other monkeys, but the digital world changes that in some ways, all of a sudden, as the article states, we can make exact copies of certain things for practically no cost.
As Starslayer points out, something that is gained without effort is not respected, but is that a problem with society, or a problem with people?
