Dragging things around is not required on macOS. There are always ways to do things without it. It's just that it's a generally pretty intuitive way to accomplish a task, and it's something that macOS embraced in a way that Windows never did. Want to trash an app? Drag it to the trash. Want to print a PDF? Drag it onto a printer. You can do it other ways, of course — right click and "move to trash", or right-click and "print".
