It can still be a lot more efficient to grab the scrollbar to jump to a section of a large document. For example, you can instantly get to say 3/4 of the way through by moving the scroll bar a very short distance, which when done with the scroll wheel or trackpad gestures could take a very long time.

The scroll bar is also sometimes a nice visual cue to the size of a document you've just opened for the first time, again something the wheel/gestures don't necessarily inform.

I have permanent scroll bars enabled in macOS too.

Related hint: Instead of dragging the scroll bar slider, you can also just option+click on the place of the scrollbar that you want to jump to.
