Indeed. In searching around to find something to compare these numbers with, I found that Walmart alone processed 10 million register transactions in 4 hours on Black Friday in 2012[1]. Even if all 70k bitcoin transactions every day were actual purchases (rather than shifting money around), it'd take 5 months to do what Walmart did in 4 hours.
