The idea is to eliminate the need for MTOs to have bank accounts. Because banks keep closing MTO bank accounts due to de-risking there has to be a better way for MTOs to trade fiat for digital currency. Therefore MTOs and senders can trade bitUSD etc. for fiat and earn a profit in the process. With a slow roll-out for BTS liquidity and fiat-pegged cryptos on BitShares blockchain this is very feasible.
