What do you think tailwind is?

It's a utility to generate deduped/treeshacken css classes - according to a config file the parent mentioned

It's not some grand framework or something.

It's literally doing exactly what the grand parent said. Define root css variables, and generate the applicable/used css classes that were used in the code

I use Tailwind for work and hobby projects and what you said is exactly what I think Tailwind is and why I use it.

I don’t understand where the disagreement is. I was only pointing out a lot of the “magic” from Tailwind’s abstraction isn’t as magical as the GP you referred to implies.
