As of Sierra(?) opening ~/Library/Mobile Documents in the Finder actually takes you to ~/Library/Mobile Documents/com~apple~CloudDocs. This the Finder stylizes as "iCloud Drive" and only has folders for certain applications.
It is still possible to access Mobile Documents proper through Terminal, but even when opening the directory in Finder directly from Terminal it redirects to com~apple~CloudDocs.
Is it possible to access the root Mobile Documents folder from Finder?
You can find the location to your home directory by looking in the "Users & Groups" System Preference pane.
Now, once you see where OS X thinks your home folder is located then you can work on un hiding it if it is not showing up where it is suppose to be.
Make sure its name does not start with ".", Additionally you can use the SetFile -a v /pathToHome command to make it visible if it appears to be hidden for no apparent reason.
Found a solution to the problem here:
Enter the following command in the Terminal window in the same way as before (no typing):
xattr -c ~/DesktopTry the action again. If the same thing happens, relaunch the Finder by selecting Apple menu > Force Quit... > Finder and pressing return or clicking Relaunch.

I found a really nice type of workaround for this from here. Essentially you need to run the following command in Terminal:
This will create an alias on your desktop that shows all the folders in the Mobile Documents folder when you open it. You are free to browse it to your liking—albeit with one caveat: you can't directly open any folders. You'll have to use the list view's ability to expand folders and then view files from there.
