You are right, we don't have access to the color palettes of the year 3000. The term is gamut (https://en.wikipedia.org/wiki/Gamut) and the point is each current system has its own gamut which is a subset of visible colors.

All of today's print systems, monitors, etc cover a certain subset of visible colors. I think we can expect the technology to improve toward the year 3000, and there will be new colors that we can't represent today in sRGB. But until then, no, sadly we don't have access to (all) those color palettes.

But hey, the colors we have today are forward-compatible.
