In the real world people can wait for many months for a house to be built with a deposit much larger than the cost of a BFL device, and they are perfectly happy with that, as long as the builder doesn't go bust and they get their house in the end.
In the real world, having just had a house built I know how this works. The builder has compulsory insurance should they default before the house is finished. The insurance company would pay and I would have an angry bank chasing the builder (the bank paid the money, not me). In the real world we all know if BFL goes belly up before a customer's order is shipped there's basically nothing that can be done. A BFL asset sale would maybe return 5c in every dollar.
I also had a due date for the house and it was finished two months ahead of schedule. BFL has missed promised shipping dates since October 2012.
