I mean, it was closed in general from the public except for those obvious.

To be honest, I never did really understand the status of the drachorn cave. IIRC, Mur once said that while it is "restricted/closed", those with access may still enter, as long as they do not do things crossing the line such as the previous lair training incident.
Now if my memory is correct, after that the cave was closed regardless of access, but then the lair keepers was formed and Indy was given access inside, which lead me to think that those with access to the lair are allowed to enter (otherwise their access would have been taken away?).
Now speaking about obvious, seeing as RJ apparently still has his access, I would assume that he is technically allowed to enter.
I'm just speaking for this aspect that you brought up, and not commenting about the other acts he did inside.
