We're not doing that. The author seems to assume that
so many people are creating new art nowadays that the entire rest of civilization is being left to rot, but that's simply untrue, and a false dichotomy.
Most artists work crushing hours in sweatshop conditions, or are constantly gigging on the razor's edge of subsistence, with what little value they produce going to expenses or middlemen. Then the internet decides everything they create should be free whether they like it or not. We value the companies that distribute art and put celebrities on a high pedestal, but that's a different thing than putting creators and artists themselves on a pedestal.
The reason no one is fixing potholes or bridges or whatever is the taxpayer doesn't want to pay for it. If the pothole isn't right in front of their driveway, or the bridge isn't on their commute, or their kid isn't going to that particular school, then people consider any taxes spent on it to be theft. We no longer have a society, we have millions of individuals that happen to share a landmass in common but little else.
