If we use mbtc colloquially instead of btc then at the current fiatola exchange rate 1mbtc is $17.00, give or take. The argument from the peanut gallery is that this will help people realize that they, too, can afford btc since lo! it is divisible by up to 100,000,000 satoshis. (Well, not really, because of the space required to store the hash of the txn index, but I digress...)
People who have not taken it upon themselves to learn about how divisible btc is have no business buying btc. And btc is for buying houses, not for buying coffee, so no thank you to switching up the nomenclature.
