Without your "bad dreams" we wouldn't have the Red Cross, Kiva, Linux (or a majority of *nix releases), GPG (or lots of other OSS projects), One, Doctors Without Borders (or any number of other non-profit organizations), immense amounts of historically important art, music, documentaries, museums...
Some of the best, most important dreams in human history weren't profitable.
One would argue that "social profit" (ie: where society profits) is where all those not-for-profit "bad dreams" go.
The Red Cross movement especially brought forward the Geneva Conventions (which improved the conditions of prisoners of war), successfully fought epidemics, and (in my opinion) began a tradition of humanism that combats extreme fundamentalism in a practical non-violent way (which is why the worst fundamentalists target Red Cross/Red Crescent workers.)
All of those things are profitable in the sense that's relevant to this context. In this context, "profitable" is clearly being used to simply mean financially viable. Nonprofit organizations produce surplus revenue, they just happen to use that surplus to further invest in the official (and legally-approved) goal of the organization.
