I don't think we will ever see this happen, the more people get access and at a cheaper price, the higher the chance of content being leaked, once a comic is leaked it looses all it's value. Moiarte has published dozens of comics, but only the few newer ones who have not been leaked are actually giving him income. People could band together into one account to lessen the monetary burden, but recently on his twitter Moiarte announced he's able to tell when an account is being accessed by multiple users, although i believe this tool is mostly being used to detect users who are selling his content at lower prices.
In an ideal world, Moiarte would make his income trough adds, like many porn sites his content would be available at his domain, and instead of striking leaker accounts, he would not care if content got stolen, because if it gets uploaded into other free porn sites it would serve as free advertising, which would flock curious new viewers into his domain, which would generate more income.
Because he's been butting heads with his pirate community by a considerable time, after getting most of his content leaked, loosing a considerable amount of income, and after creating a reliable piracy countermeasure system, i fear it might be too late for him to consider a different approach to his business model.
