Why do people beg for cash shop stuff?

[Talraen]

It would be that simple if XIV was the only game being produced by Square Enix. However, as it stands, that money could be going into any number of projects - not necessarily back into XIV.

Yet we know the following:

1.) People use the cash shop
2.) The next expansion has a higher budget than the last one

Aside from not liking the cash shop, do you have any reason to conclude that it hasn't helped the game financially?
