Yes! If you really believe you have a solution to a problem, then it makes sense to execute that solution in a way that doesn't scale, to verify that, with infinite resources, the solution works, and it feels good. This is a necessary, but not sufficient, condition for what comes next, which is (roughly) about making the production more efficient with technology. If you can maintain the utility of the solution and drive the cost down, there may be profit in those hills!
