Packie didn't choose not to play, he wasn't wasn't given the choice. He was driven out of the sessions by people who had no interest in traditional music, but rather came to play (with) themselves, and the music they brought with them had little to do with what had little to do with what Packie and his brothers played.
Happily, Irish music has moved on from those days - we may have lost Doolin to the cowboys, but we have plenty of other sessions to make up for it - and it won't be too long before there's a MacDonalds there.
