interesting thought experiment... am i correct in understanding that for this to apply, the pendulums plane of movement must not be perpendicular to that of the ship itself? additionally, when the pendulum swing's direction is in the opposite direction of the ship, it would still move even in the case where the ship is moving at c, correct?
i agree with you, but i also think that there are some things that are more important, and deserve to be protected outside of the dynamics of the free market. i'd argue that art is one of those things, along with housing, health care, social services, etc.
