The goal is to work in MS Word but save it in Google Docs. Somehow smoothly, right from MS Word, without copy/paste. Is it possible with Google Docs?

You can use Google Drive to work with Microsoft Office files in two ways:
- From web browsers or with sync clients
- Directly from your Microsoft Office programs
To use a web browser or sync clients, learn more about using Google Drive apps.
Google Drive in Microsoft Office
You can install the Google Drive plug-in for Microsoft Office. The plugin works with Word, Excel, PowerPoint, and Outlook (2007, 2010, 2013, and 2016). You can also use Office 365 if you subscribe and install it on your computer.
After you install the plug-in, you'll see "Google Drive" in the Office menu bar.
Note: The plug-in does not work with Office for Mac.
Follow the link at the top of this answer to find out the specific instructions.
If you install Google Drive on your PC it basically creates a directory you can browse to like any other folder on your computer. You can save the word document to that folder.
As an alternative you can flip it on it's head and work on your MS files from Google Drive with this Chrome extension from Google - Office Editing for Docs, Sheets & Slides
From the extension description:
View and edit Microsoft Word, Excel, and PowerPoint files with Google Docs, Sheets, and Slides
