Well, Venus doesn't generate its magnetic field via geodynamo. Instead, it has some sort of weak magnetosphere induced by the interaction of the solar wind with the planet's ionosphere.
Also even without this magnetic field, I guess the volatile processes on the surface are enough to keep the atmosphere going.
They must have some marketing strategy already prepared. Similar to that of Beats by Dre. Just make it popular trough popular culture (movies, music videoclips, interview with Hans Zimmer wearing these) and the kids will persuade their parents that they just need to have it. Thats how the bandwagon picks up speed.
