That wasn't the MPEG design goal. It was to stream video through a distribution network where dropouts would be tolerated as part of doing business. People were accustomed to snowy analog broadcast video. That is more disruptive when listening to purely audio. This is incidentally why CDs had their error handling significantly improved over Phillips' original prototype which would have been much more susceptible to scratches if commercialized.
