Why do people beg for cash shop stuff?

[Blood-Aki]

For the same reason people buy gill, Lazy, It does not require any work, and you just need real money to get it instantly.

[Zojha]

[...]It does not require any work[...]

Except the real work you have to do to get the real money.

What's really worrying is that SE apparently is prone to make things so unenjoyable to obtain, that people have built up expectations which makes them a priori prefer spending real cash over doing what they fear SE would have them do otherwise.
