Regarding being "'used' & shouldn't be unnecessarily cosseted" I would agree in the sense that where museums adopted the Gothic architecture of churches in the nineteenth century to make visitors conform to a standard of behaviour infused with reverence, as well as presenting extensions of evidence of God's work - look and don't touch or ask questions isn't the invitation to engage required to broaden interest in and see ancient remains preserved. What we do need though is an identifiable line in the sand in order to protect through respect and both guide future enthusiasts and foster a nation of monument enthusiastic guardians who just might campaign and object when it matters as well as saving monuments in the field.
