I use page builders every day despite being able to code, I think they're great but they all suffer from the same issue. The developers of the page builder tool need to decide what you can change and what you can't, and it's purely subjective. If you make absolutely everything editable you've just replaced editing CSS with a GUI (more or less Webflow) and you can't hand over a complex UI to a non-dev. I don't know how you solve this problem.
