It doesn't matter what dates or time taspeotis picks; his point is that at any date and time Bitcoin is too volatile to meaningfully function as a currency.
No major currency suffers from 30% intra-day volatility against other currencies. It would make pricing goods and services essentially impossible. Who would care about saving up to 5% on credit card fees if they're suffering 30% arbitrage losses because they set/update their prices at the wrong time of day?
