Don't despair if you don't have a camping ticket and definitely DONT PAY $400 for a camping pass. Wait until 3 weeks prior to the festival!
Yes, the scalpers bought every available ticket. However, they are not going to the festival, and don't even have the camping ticket in hand yet. It would be a huge mistake to pay someone for a ticket they don't have!
2-3 weeks prior to the event (end of March), all the camping tickets will be delivered to the scalpers (and also to the real people who were just on it, go you!). That is the time to buy. They will have a mountain of tickets in hand and everyone will have already made alternate housing arrangements. Result? camsite will be empty and tickets will return to normal price. I bet you will be able to buy a camping ticket for $50 on April 7.
