Yes, if we scale down out projects we can write custom CSS for our HTML without the need for specific class names that refer to specific CSS aspects and make it more readable, but that's not what frameworks were built for, and comparing the two like this is disingenuous.
The left picture has everything I need in that screenshot, the right picture would require me to work out how specificity rules cascade down to each DOM component to even start thinking about what to edit.
This is a great showcase of why people ought to choose tailwind if they value their time and just want to get on with things in the real world.
