OK. Say there are two people networked to each other, and neither has any Bitcoin at all. Can one of them purchase 10 Bitcoin worth of services or merchandise from the other, be debited 10 Bitcoin, and run a negative balance of Bitcoin, without having to start with a positive Bitcoin balance? And then bring the balance up to zero by selling 10 BTC to the other person later? If so, it's a non-scarce system. If not, and they had to have a positive balance to start with in order to make a purchase, then it's scarce in exactly the same way as a gold-based system.
