I don't understand frameworks like this. You are basically tying presentation with markup. God forbid you want to create more than one theme for the same HTML!
The TLDR is that you don't lose anything by starting out this way, because at any point you can extract (think @apply) higher level utilities or semantic classes, but gain that you can get a good looking design in place quickly by having useful constraints, not needing to switch context all the time, and not being forced to make up names for everything. While few sites need to conform to the "Zen Garden principle", Tailwind won't stop them from doing so, if you put in the work that it makes optional.
