I am going to assume that you are an older person who has no real experience with "piracy" because the tone of your comment suggests a misconception about how it works. "Pirates" absolutely will pay. They pay to get the content as soon as it comes out and in high-definition.
There are large and influential companies that have come to recognize the piracy is the result of failures of distribution, not pricing. The prime example would be Valve, which since it made Steam its primary distribution channel, had paid very little attention to piracy (compare to EA). The CEO, Gabe Newell, has discussed this publicly, and you can find him discussing it on YouTube.
His example, which is particular to the gaming industry, but applies also to feature films, is that it is not reasonable to think that individuals who can afford $40/month internet connections and $2000 gaming rigs are pirating games because of money. They pirate games because they cannot get them legally conveniently and readily. This is particularly true in countries where English is not spoken. It takes months for a game to be released in Russia in Russian after the game is released in the United States. If a gamer can get a version in Russian faster via piracy, he's going to do it. The same rule holds for feature films, where again, release dates are not universal.
As to your second point, if you cannot see the common sense in the idea that the millions of American and foreign young people who do subscribe to cable or to HBO but who enjoy Game of Thrones want to be able to watch it online in high def the same way that they watch every other show, I think you're just trying to argue for the sake of it. Even if only 10% of these people paid to watch it on HBO/iTunes/Amazon, that is money that HBO is not getting now. Being able to pay a few bucks to watch the episode the same night that it is released in high-definition is well worth it. To take just one demographic, college students living in dorms do not have cable subscriptions. They all watch the show by streaming from sites that violate copyright or via file-sharing.
Perhaps you do not know this, but it is trivial to watch shows online. You can stream video from dozens of sites, with more of these appearing every month. These sites upload new episodes with hours of their original airing. That being said, Netflix has millions of subscribers, including very many young people who know how to watch shows like this. Young people also spend lots of money renting movies and television shows on iTunes that they could find for free online with a little effort. People pay for a high quality stream without the annoyance of pop-up ads and banners, and they like fast downloads and ease of use.
Here's Gabe talking about piracy, so don't take my word for it:
