Not sure what you mean exactly. Google certainly expected to make money from copying the books. This is no different than Sony expecting to make money when it allowed purchasers of its beta max players to copy the copyrighted works of others. The issue is does Google's actions deprive the copyright holders of money, and does what Google did benefit the public. I'd say Google's action in copying the books was likely to make the book publishers money, and it definitely would have benefitted the public.
The analogy with Betamax is hopelessly flawed. In this instance, the manufacturer(s) of the scanners Google used to pirate books are in the position Sony was in in that case. Google is the guy using Sony's recorders to produce and sell pirated copies of copyright holders' works. Making the recorders wasn't illegal, because they had legitimate uses. But the guy selling pirated copies was still breaking the law.
And the answers to your questions are yes and no, respectively. It's ridiculous -- and either disingenuous or clueless -- to even ask if copyright holders were deprived of money. And, no the public does not benefit by undermining intellectual property law, particularly not copyright law.
This is a red herring & ad hominem that has absolutely nothing to do with the legitimate issues here. So, no, it's not worth noting.
