I don't think pg intended that crazy new ideas require someone to be a domain expert, just some expertise. Slight wording difference.
In the case of music, one could have domain expertise on audio files, compression and domain expertise about file sharing and domain expertise about younger people's listening habits. That's just having some insights into the domain, several as is the case with Napster. Music industry execs in those days probably had domain expertise on contract law, revenue sharing models, marketing and didn't have a clue about file sharing or audio compression.
Also want to mention the examples you mention seem to have not much "newness" to them to be "crazy new" in my opinion.
When I think of "crazy new" ideas, I think of things like stuff that came out of PARC in the 60's. If you go watch the Stanford 2 part series "How To Invent The Future" with Alan Kay on youtube [0] it goes into a lot of detail about them.
The challenge there with Xerox was they couldn't capitalize on every single idea that came out, just not logistically possible for a company to really do that.
