If it costs $500,000 to produce a record, like she says it does, that would create limited room for a great number of bands and artist to record. The market size ($s of world wide discretionary income) can only support a certain level of production.
Figuring out how to lowering that number would be far more productive than trying to create the next huge app which helps starving artists with terrible recording quality get their music heard or some other distribution method.
(She also fails to add in concert revenue which may be lucrative for artists)
