I was wondering what preserves the value (vale of one commodity vs the other) and came up with these thoughts:

Gold

• The amount of gold in circulation remains almost constant.

• Small amount of new gold is added to circulation every year through gold mining, but it’s a small % of the total already existing.

• The existing gold retains its function for many years.

Real estates

• The number of flats/houses in use remains almost constant.

• Small number of new flats/houses is added to the market every year through construction but it’s a small % of the total already existing.

• The existing flats/houses retain their function for dozens of years.
