How do you estimate the monetary value of the following? Is there any rationality in any approach adopted?

• The resumption of a person’s house (perhaps in order that a road can be widened)? (Refer to the movie The Castle, Village Roadshow, 1997, where a distinction was made between a house and a home.)

• Dislocation of a community by routing a road through the middle of a neighbourhood?

• The loss of habitat of an endangered species of flora or fauna?
• A national park? A suburban playground? A tree?
