I've personally seen the physical teapot in the Computer History Museum. We routinely make detailed simulations of how such a physical teapot interacts with visible wavelengths of light, specifically for the purpose of comparing them with reality. From this we know that we do in fact have the ability to simulate this aspect of reality to a high degree of precision. The ability to detect gravitational waves is just recently coming on-line, and we have no example of an actual warp drive to measure, so the simulation in this paper is theoretical to a much larger degree than that of the teapot.
