I believe, not only ubuntu, but for any linux distro , if you dont setup a
bootloader password on your machine
, its very easy to get admin access and run any of the commands from the
single user mode.
Its a common practice by linux admins to use single user mode to recover
lost root password.
If you are concerned about physical security, you MUST setup bootloaded
Similarly, its also possible to boot using boot cds and mount partitions on
your system and access data without caring about the permissions etc.
So what you say is a flaw, is in my opinion should be addresses under
