I agree whole hartedly.

Some places present themselfs very accessible for all who would like to visit like the monument Stonehenge or the uprights of Avebury, it's nice to share.

But there are many different levels of approach to the different historical features.

You have a important point here.
Tampering and vandalism both need to be questioned.

Also we will need more archaeology orientated teams to do research.
And less evaluation and/or assessment teams.
Refering to the objective not a person or one of the professions.
