red:

actually - this is also a good point... and I have made this change...
however, I still really want the user "rooted" to their home directory -
I just believe that is a much cleaner, safer, more professional appearance.

I'm also thinking about user maintenance. If I know that all users will be added by default - "rooted to their home directory", then the maintenance of users is a task I can delagate.

Yes, I was talking about virtualization per user.

Anyway, why not try selinux? RSBAC? grsecurity? I think you're looking for MAC/ACL implementations (they're hard to maintain but provide ultimate security)

createhomedir(1)					    BSD General Commands Manual 					  createhomedir(1)

NAME
createhomedir -- create and populate home directories on the local computer. SYNOPSIS
createhomedir [-scbalh] [-n directoryDomainName] [-u username] DESCRIPTION
createhomedir provides several options for creating and populating home directories. OPTIONS
-s creates home directories for server home paths only (default). -c creates home directories for local home paths only. -b creates home directories for both server and local home paths. -a creates home directories for users defined in all directory domains of the server's search path. -l creates home directories for users defined in the local directory domain. -L causes the created home directory to be localized. -n directoryDomainName creates home directories for users defined in a specific directory domain in the server's search path. -u username creates a home directory for a specific user defined in the domain(s) identified in the -a, -l, or -n parameter. If you omit the -a, -l, and -n parameters when you use the -u parameter, -a is assumed. -i reads username list from standard input and creates specified home directories. Each username should be on its own line. -h usage help. FILES
/usr/sbin/createhomedir location of tool CAVEATS
When using the -a option, search limits of various directory servers (such as Open Directory or Active Directory) can prevent all possible home directories from being created. In this case, you may need to specify the usernames explicitly. Mac OS X May 31, 2019 Mac OS X
