Is this really an argument for Tailwind though? isn't this just an observation that both approaches seem to converge when the systems get very large and complex? At which time the work and effort is the same, except ..in the case of Tailwind you're using a made up syntax, and when writing similar amounts of code using CSS you can do it using the CSS standard. The key difference is that you would have to hope that Tailwind outlives CSS as a standard in terms of tooling and language support and continuing improvements (evolution) over time.
