This analogy doesn't map very well. It's a clearly different medium. The value of a store is the ability to buy products from it, you taking a photo of it doesn't impact that transaction of value that at all. The value of content online is the very act of reading it/consuming it. A scraper is getting a free lunch, that is clear. They are trading nothing for something, and as the owner of the something that is not the deal I have chosen to make.
