That page doesn't say that the default access is no.

access:conditional won't work here, because the closing times are irregular. The lift gate is usually open, except during military training.

In my opinion, access=* (certainly access=permissive) can be considered on the road, but not on the lift gate here. access=* is meant to specify permissions rather than physical restrictions. A closed gate is just a reminder that the road behind is forbidden. Nobody cares whether the gate itself is operated.
