The truth about virtual goods

You know as well as I do that when you are playing a Free-to-play(F2P) game, chances are that there is bound to have an in-game shop that allows you to purchase in-game goods with the use of real cash. So then, what exactly is the point to spending real money to buy virtual goods?

1. The game makers will earn money. As buyers, we are ensuring that they get paid so that they can update and improve the game further.
Though this may sound like the game developers are creating games for the mere sake of earning money, this fact is true. However, if the game developers were to consider a different option of earning money for example, instead of a F2P game, the game will be paid subscription. However, if the game fails to attract players, the game itself will lose more than it gains.

2. I buy virtual goods so I can brag to my friends.
This may be true to some extent. Take Trickster Online for example, the game has a cash shop(It is called MyShop in the game but players like to call it MyHax) which sells powerful equipments for real money. Players who are able to burn excessive amount of cash are able to purchase these overly powerful equipments and finally ruining the game. This somehow created a sense that people who are unable to buy these equipments are weak in the game. Excessive bragging in the game then led to the game developers patching the game to fit the requests of the buyers.

3. I look great in that, I want it.
This opinion may be biased in reasoning but is also why many players are willing to buy virtual goods. Take AdventureQuest Worlds for example. The game does have in-game equipments that is purchasable only via real money. However, those equipments have absolutely no purpose, stats or use other than fashion. But because these equipments are not only slightly cheaper than most virtual goods out there, they look great.
