Important things take resources to do. "Forget money" is OK for hacks and self learning tasks, but being mindless about how resources are spent is how dead end jobs, industries built on fossil fuels, pedestrian hostile towns, and overly complex web frameworks happen. Money isn't the only resource. Time, energy, attention, natural resources, and other finite things also exist. If you aren't making something less resource intensive for somebody, it's just a fun hack. Which, maybe that's what you're shooting for, but it's also a local maximimum.
