Problem with Concorde was not price but reliability. They were dangerous to pilot and felt a few times, imagine that uncontrolled thing falling on some poor village? money is not the issue, usually, otherwise military would still fly a "Black bird", right? Technological challenges, like temperature of jets and ability to stay in control if something goes wrong is more important. If your Boing looses an engine, you will still land it. Try that with Concord.
