There exist many successful screencasts businesses. I think the main problem with "subscribe monthly for unlimited access and new screencasts every month" is the "new screencasts every month" bit. That is an issue with the business/charging model, not with publishing screencasts for money. There's no reason why somebody with a back catalog of 200 episodes who doesn't have desire/bandwidth to record more can't sell access to the back catalog and fairly easily get to $X00,000 per year.
