I think that the reality of file ownership on a Personal Computer is
determined by who can put their finger on it.  Try this:  put your
finger on a floppy disk, or on your hard disk drive.  You own all
that data.  If you can touch it, it's yours.  Never mind what the OS may
try to prevent you from doing with it.

This goes with my other philosophy, about granting user account
privileges on any computer system.  The user that can reach the power
switch has all the privileges, and you'd better get used to that.

No "personal computer" can guarantee this.  When your friend sits down to
your Amiga, he can reach the power switch; see what I said about "user
account privileges" above. :-)

Now, I can imagine that this Amiga might be part of a network
(imagining, of course, that the current state of Amiga networking
improves) where there are multiple users on a network, and the network
allows file sharing between network peers.  In this case, it
is vital that your Amiga only grant access to those files you
specifically want to export.  They are your files, after all.  And you
may even want to decide which other user is granted access.  So now
"file access rights" begins to have meaning, but ownership is *not* in
question.  They're your files if they're on your disk.
