I think it should be multi-token for the same reasons you expose, at the same time exchanges will provide dash-tokens the same way Bitfinex does with USD-T to simplify fiat-token conversion, all parts can be easily provided by DASH becoming the world authority on digital commerce.
I haven't heard one single reason why this route shouldn't be studied in depth.
I wouldn't be surprised if USDT collapsed within the next 12 months.
