> why would the temperature at any finite point will always be zero
Based on your answer of the temperature inside a neutron then maybe it won't be zero everywhere. Any finite point is going to either be inside a particle or outside of a particle. And since most of space is empty, and atoms are also mostly empty, the vast majority of finite points will be where there is nothing, and hence have no temperature.
> emptying space is stupid expensive
I don't what this means. Most of space is already empty.
