Unfortunately the podcast was recorded in the US. For people sending money domestically in the US, like SBF was proposing, it's more likely to be 1-2 business days of latency (so add 2-3 days to that if you happen to try to send it on the last weekday of the week, naturally) and consumer banks commonly prevent such transactions from occurring at all. For example they may impose much smaller limits on the daily amount transferred, so the client must make phone calls and pay fees on many different business days. The situation is a bit worse for US people living outside the US. My baseline experience for cash transfers between my own accounts involves about 1 week of latency and some phone calls at like 2 in the morning :)
