Giving herself access shouldn't be a security issue.

It's a huge security hole changing the ownership of everything to any admin ~user. This is the equivalent of enabling root user login and always logging in as root user. While the admin ~user is logged-in (on a Mac with all ownerships changed to admin ~user), anything can be installed anywhere without any notification to anyone. It opens your Mac to almost anything by eliminating all notification or need for password authentication to change literally anything. Luckily the fix is easy enough, simply running Disk Utility>Repair Permissions. It may take a while with 100,000+ files needing repair.
