Professional musicians these days earn their living by going on tour and selling concert tickets and merchandise (esp. T-shirts). The biggest ones are quite profitable, and the concert ticket prices I've seen lately are rather high ($50 to sit on the lawn, $200+ for seats, for one big concert in my area).

The problem is getting to that level where you have so many fans that you can fill an arena or even a smaller venue.

It was a metaphor. It wasn't intended literally. The actual discussion here is about monetizing open source.
