I have to agree with this. I have, in the past, infringed on copyright (I no longer do this, as I reformed and whilst I am diametrically opposed to placing undue restrictions on creative work, I also think it's not something I want to break the law over). However, on many occasions I actually purchased the work that I infringed upon, and in many of those instances I don't think I would have paid any money at all to the author of the work because I didn't realise how valuable it was to me until I had (what's the word?) consumed it.
In fact, this is sort of like pirating music, movies and TV shows - in particular music. With these items, it was increasingly the case that you didn't know you enjoyed the work or liked the artist until you had actually experienced listening to or watching their work. Most people have a very finite supply of money, and so if they decided not to infringe copyright then they would just decide not to buy the works.
This is why the record companies were so incredibly stupid in not getting behind streaming services, instead attacking people with little resources for infringing copyright, such as suing mother of four Jammie Thomas-Rasset to the tune of $1.9 million.
Apple and Netflix have essentially eaten their lunch because they have basically freed up content for a reasonable subscription fee. Apple iTunes was great even before Apple Music launched because you were finally able to purchase individual tracks instead of having to buy the entire work - and at a price that pretty much anyone could afford.
Which is why I get so annoyed with rights holders dividing the globe into geographical regions. They do deals with big companies to maximise their profits, but this is perversely leading to increased copyright infringement and the bypassing of their geoblocking efforts.
In essence, these distribution companies add almost nothing to the work produced by the original creators and artists, yet take a cut anyway and inflate the price paid by the consumer of the work. Sometimes it's even more perverse - as an example, I tried to purchase the Dragon Book on compilers from Amazon in eBook format to read on my iPad 2. This was not in any way possible to purchase, so I ended up purchasing the physical book from the U.S., had it shipped to Australia and found an unencumbered PDF with the content so I could read it on my iPad.
In the printed world, this is currently the problem Elsevier and other companies are facing. They have restricted access to important research by in effect gouging the market, and so students from overseas countries (in particular in some Eastern-European nations) who could either never gain access to the material or couldn't afford it eventually just shared it and never paid for it. Then they got organised, and suddenly publishers discovered that they had a massive problem on their hands with no way of effectively countering it because those pirating the material are outside of the jurisdiction of the U.S.
