I didn't see Coast of Utopia, but I think it was a similar length/division of parts. The play certainly seems worth devoting three nights (or one very full day) to, but I agree it would never make money. The Norman Conquests had what I think was the ideal schedule, was absolutely brilliant, and still couldn't make back its investment.
I could absolutely see a producer who wasn't focusing on/interested in a profit doing right by this work. That said, I personally think any producer who hopes to make money on the production is on some drugs I'd like to get my hands on.
