Because a) you don't have to if you can get a bank guarantee and b) you get the money back including interest (an addmitedly measly sum but so is all interest).
It's not ideal. For some it's a stepping stone, for some it's a way home and for others it's a way out of where they are now.
Personally unless necessity dictates otherwise I wouldn't go there. But I know several people who have and none of them have regretted it.
Although the real argument I wanted to make is if you're going to use figures to bolster your argument at least make sure they're accurate.
