Trademarks are inherently geographically limited. They apply in regions where the trademark holder does business under that name, not over the whole world. The bizarre part is trying to apply their trademark to an area of business that is not related to what USPS does. USPS does not play music gigs. There would be no danger of someone confusing USPS with a band. Trademarks are also limited to the line of business that the trademark holder operates in. This is why Apple Computers and Apple Records (the record label for the Beatles) were able to operate without trademark conflicts for decades until Apple Computers started getting involved with music and then needed to come to an arrangement with Apple Records.
