Information has a non-zero cost for the first unit, and zero cost for each unit thereafter. In other words, marginal cost is zero. These types of goods are hard to find a market equilibrium for.
Paul Samuelson[0] makes the argument here[1] when discussing how lighthouse economics works that anything with zero marginal costs that has a price other than free is by definition an economic loss. Therefore you should find other ways to fund lighthouses, and by extension, all media and software.
I'm not sure that's true. You're describing just about every SaaS out there. (Yes, there's some per customer cost of resources and sales/support but in general relatively little compared to initial and ongoing development.) What is true however is that you need to be able to prevent people from acquiring your product/service for that very low or zero marginal cost.
