Why should Counter-Strike: Global Offensive cost more?

Counter-Strike is a really popular game and since Global Offensive introduced the matchmaking-mode there are a lot of serious taken games out there.

Now Counter-Strike: Global Offensive costs around 13 Dollars and like 3 and 6 Dollars in Sales.
What is wrong with those low prices? Well, there are a lot of hackers out there. People are buying a lot of counter-strike: global offensive accounts just for hacking on public or matchmaking servers.

What does that mean for us? We have to deal with a LOT of more hackers and personally I prefer to buy a 30$ Game and play without hackers instead of 3$ and having hackers in all games.
