And many of those economic reasons were caused (or influenced) by regulations.
The Concorde was only allowed to fly supersonic over water, making many potential flight routes are impossible. The New York to Mexico City route Required it to drop from mach 2 to mach 0.95 while flying over Florida before accelerating back up to mach 2, wasting a huge amount of fuel in the process.
Originally it wasn't even allowed to land in the US, with Congress banning it outright. It wasn't allowed into New York until a year after its introduction.
Sure, the larger issue was that it made too much noise in supersonic flight, maybe you could fix that in a newer aircraft. But with all the regulatory issues Concorde faced in it's lifetime, companies are disidentified from trying.
