Sorry, dude, but your logic is a bit flawed. Not everyone would choose PC not just because of money.
Gaming on a console is a matter of convenience. Not everyone is tech savvy or has the patience to build the perfect computer and optimize everything. You know that the controller you use will work, unlike pc's where depending on the game, it can be a nightmare to make them work. Took me forever with my xb360/pc controller. Such a pain in the ass.
Then you have stupid things to worry about, such as antivirus going mental on you because it doesn't like a file from a game you want to install, obligatory installation through steam, uplay servers being offline and not being able to play your game at all, and so many more to name.
All I know that when it comes to my ps3, all I have to do is insert the disk and (if an installation is not required), my game will work just fine. Peace of mind matters a lot to me and I'm sure many others.
I also tend to keep the big tv in the living room and having a pc in the living room is not that easy, while with consoles it can be a different story.
