You don't need them at Waterloo as Bank is gated and there are no
intermediate stops.
So? You can get transfer onto another line or the DLR via the passageway.
The point Mr Thant is making is that in a sense Waterloo W&C line
offers ungated access to the LU network. As a response I'd say that
it's pretty much impossible to enclose the LU network in a
hermetically sealed bubble.

You can enter via the Finsbury Park - Moorgate link, too, and I'm sure there
are others. But so long as one end or the other is gated, 99.9% of journeys
will be monitored at some point.

Plus it's only a question of time before DLR is under pressure to improve
security, especially once the six-car trains get moving.
