the GPS traces are recorded by volunteers and uploaded to OSM. There is no management. Apparently more of those people recording such traces are visiting the Dollar Store than the courthouse. That’s it.
In short, they used to be more important before we had access to high-quality aerials, and were (and sometimes are still used) to record location of roads etc to make their mapping possible (or easier or more accurate).
In some cases they are still needed and useful.
people happened to record these (and shop has few of them anyway)
probably they recorded while visiting shop and were lucky enough to not have anything to handle at courthouse
in short: mapping the world and sharing this data with others
people map different things, some map cycling infrastructure, some hiking trails, some Flock cameras, some sculptures in parks or sidewalks or roads or shops or churches…
