While this is ultimately true, one can make it quite hard for an
attacker to break into the system undetectably. The unpreventable
break-ins all need at least one power-cycle, which is usually hard to
hide. Slipping in a floppy and executing /mnt/floppy/rootshell costs
only 5 seconds, and is quite stealthy.

In your reasoning, nobody should lock their door, since a robber that
can come near the house could always break down the wall. You ignore
that one action will put the bad guy in more risk than the other.
