Yes, Tailwind is inline styling with much better ergonomics. Why is that not enough?
Yes, you may not end up with a coherent, harmonious design governed by mathematical relationships, but that's not an argument that the resulting product is not perfectly fine, nor is it an argument that your productivity is higher if you spend a bunch of time to learn how to define "visual harmony through mathematical relationships" as expressed in CSS, then go through the process of designing such a system that's suitable for your app before you even start building your components. The fact that you are typically developing your UI in concert with other features of your program is exactly why front-loading this design system effort probably results in wasted work as you rapidly iterate and evolve both. I think this is why Tailwind has become so popular, because it requires almost no front-loaded effort, and so iteration is rapid.
If you're not already persuaded by puritanical aesthetics around this stuff, then justifying this sort of front-loaded effort will probably be difficult. If it does turn out to be difficult, that probably means this approach will have a smaller niche than perhaps you're hoping for. Best of luck!
You seem to mostly be arguing for a "~fine, but at least it was fast to develop" outcome, which is certainly one choice. But doing this sort of upfront work is for when you're not just looking for ~fine but something more. That's why sometimes you have to "waste work" to find better ways, even if it takes longer time. R&D basically, but for design.
But there is a time and place for it for sure, not every project is about coming up/producing something "perfect no matter the time/energy". Similarly, not every project is about "getting something OK out there as long as you get there fast".
