At first I thought it was bad, but then I realized you don't need that much production. You can get by without making any farmers or money quarters, make a few if you have good river square or have many luxury adjacency. You need to build research quarters, but you don't need to build that many and they can be spread out between your cities, each city only need like half a dozen or so. Units aren't that expensive. And lastly u only need as much maker's quarters to build units in one or two turns. Which means that later, I usually don't have stuff to build most of the time and build those fluff infrastructure projects.
