... by manipulating the Finder to:

(1) Create a snapshot of the entire file system; (2) or find a recent Time Machine local snapshot; then (3) mount the snapshot obtained in [1] or [2] without owners enabled, effectively granting Alice read-only access to other people's files without having administrative privileges.

The Finder doesn’t create or mount APFS snapshots. And while I haven’t tested it, I fully expect Time Machine to still enforce Unix file permissions. You really need to be using the command line to do what you’re describing.

I haven’t tested the Finder case though. Nevertheless there is the `tell ‘Finder’ ... do shell script ... end tell` construct that _may_ be able to get the Finder to launch an arbitrary subprocess (and may inherit full disk access) just like how Terminal would.

However I’ve tested mounting a local snapshot using the Terminal having full disk access and found out that it is possible to mount a local snapshot and make the mounted copy ignore Unix file permissions.
