PT Barnum was right. There is one born every minute.

If you read the interview, it's clear that she believed she was making an investment in herself, betting that the publicity surrounding the purchase would get her a lot of attention. She's bet correctly, it looks like.

If it ends up leading to exactly the outcome she wished, and she couldn't have otherwise achieved the same outcome for less than 10K, then she's done pretty well for herself, no matter how stupid it sounds at first glance.

Are you mocking me, James Franco?

The description sounds exactly like a magical artifact in dungeons and dragons. Well played, Mr. Franco.

"The air you are purchasing is like buying an endless tank of oxygen."

But it's mostly nitrogen, James Franco. Doesn't seem quite so endless now, does it? And if we lock you in this tank full of water it doesn't seem endless at all. Where's your precious air now, James Franco? Oh, that's right...YOU SOLD IT!

some people say not to worry about the air...

This lady spent $10,000 on the publicity that you are helping generate. There might be a sucker, but it's not her.

@Andy: Considering the limited shelf-life her notoriety will have, I think she overpaid by about $9,000.
