For example I have some last gen hue lights 1100 lm. Their color temp goes from 2000 - 6500 K. Why is that? I mean the are RGB, they can do pure blue and pure red, so they should be able to do any temperature, no?

The color temperature refers to black body radiation spectrums. At too low a temperature, it would just be a dim red (or eventually just invisible infrared). At too high a temperature, it’s basically just white already, it might shift to being slightly blue but not that much.
2000K - 6500K is about the limit of what black body spectrums could reasonably be converted to RGB colors.
Here’s another source talking specifically about light bulbs with some comparisons:
