Why move mesh up in edit mode?

Yeah it's just that in sculpting, all the modeling rules basically go out the window and you're free as a bird to play with clay. No quads or tris to worry about, objects origins, loops flows, it's as if society rules broke down and now you can enter a supermarket and take whatever you want without paying and there's no consequences. And you're like ah man this feels good, we're free. But then someone comes with a gun a robs you and you realize there's no police no more and his not going to prison, so after sculpting do your retopology, we need them perfect mesh behaving correctly.
