There's no magical extra that I know of, but you can create a plugin or snippet to do everything automatically. It's not a trivial job, but once it's working, you can sit back and relax without worrying about forgetting a step.
This part of it is relatively straightforward (assuming that you have the user object). It could be a postHook for the Register snippet:
(untested and off the top of my head)
/* username is used for resource, user group, and resource group name */
$uName = $hook->get('username');
/* Create the user group and add the user to it */
$userGroup = $modx->newObject('modUserGroup');
$userGroup->set('name', $uName);
$userGroup->save();
$user = $modx->getObject('modUser', array('username' => $uName));
$user->joinGroup($uName);
/* Create the User's Resource and Resource Group */
$doc = $modx->newObject('modDocument');
$doc->set('pagetitle', $uName);
$doc->save();
$resourceGroup = $modx->newObject('modResourceGroup');
$resourceGroup->set('name', $uName);
$resourceGroup->save();
$resource->joinGroup($uName);
return true;
You'd want to add some sanity checks. I think the 'username' entered by the user will be sanitized before it arrives, but check to be sure.
Creating the ACL entries in code is trickier. (It's easy to do, but it's difficult to figure out how to do it). TBH, I've never done it. But at least the above will eliminate some of the drudgery.
You've probably seen this, but for others trying to do the same thing:

BTW, there's a whole other approach that doesn't involve the permissions system at all. You just make sure the user's username is at the beginning of the pagetitle and use a snippet to redirect any user whose username doesn't match. The down side of this is that, unlike what you're doing, it has no effect on Searches, Menus or getResources calls.
I should also mention another method that works very well in some situations. If you add this line to the code above, just before the $doc->save() line, it will make the user the creator of their own page:
$doc->set('createdby', $user->get('id'));
That will allow you to use NewsPublisher, keep the users in the front end, and only allow them to edit their own resources:
