What? What context? The scale is the same as Celsius which is derived from the properties of water. And 0K is when there is absolutely no heat energy in the thing being measured. There is no context where this is not the case.

Zero kelvin is very contextually useful. Put very simply it literally relates to the motion of atoms. At zero, they move zero.

The context of.. reading the fabric of the universe?

You're right, that is totally irrelevant to.. a physicist.

I see you're trolling, so I look forward to your condescending response, but to be successfully condescending you have to be at least somewhat convincing in displaying intelligence, if you can manage that then this whole argumentative act will go much better and people will get much angrier.

TLDR, Try the same troll tactic but with less incompetence for better results.

Halving something requires a scale...

The scale doesn't matter, double is always double. No matter if expressed in 1m is half of 2m, or 3ft is half of 6ft. Same is true for temperature, als long as the zero point is fixed.
