1. BitCoin has nothing to do with a gold standard. Because there's no gold. To be more precise, this issue only matters if the entire economy were to become BitCoin, and this isn't going to happen. BitCoin is a niche--distributed, zero-trust, low-overhead money. If his argument is true the only consequence is that the whole economy won't become BitCoin because it will be outcompeted in other sectors of money usage: not that BitCoin will fail.
Technologies have a tendency to escape their little niches.
