Although you feel you have been personally damaged by this, which I doubt to be honest, I do think it has been an interesting debate for a number of reasons.
As you are aware from these threads, there are those who feel that the best way to protect certain delicate areas of caves is to keep them in obscurity. Now, I would ask them how someone in your position might be able to get to see these places.
I have been accused - and doubtless will be again, I don't care my shoulders are broad enough - of being everything from overly bureaucratic to 'controlling' to 'elitist' for advocating controlled access to delicate sites in terms of physical barriers, gates, and using warden/guide/leader systems. In the case of someone such as yourself, that means that you could gain access to such places, accompanied. Is this a better or a worse answer than theirs, which may strike some as being far more elitist than my approach, I wonder?
There are, of course, difficulties with all methods. In the case of the gate that was removed 'before the cement was even dry' I do wonder how the vandals would have been prevented from finding out about that find.
