The Treasury is responsible for minting new tokens, though cannot do so without the express consent of DAO members. Whether that’s multiple people pledging to a crowdfund; one individual member funding an entire land acquisition or DAO members permitting donated land to be acquired. Therefore, the DAO has full control on token supply.

As a fungible token every GST is of equal value and does not represent individual parcels of land. 

This means that once land is acquired no additional GST can be minted in relation to that specific parcel of land. Therefore, the Treasury can only mint new tokens once new land has been acquired and is held by the DAO, meaning that the only way to mint more tokens is for the DAO to acquire more land.

As with the ‘Gold Standard’ where there is a finite amount of gold in the world, there is also a finite amount of land on Earth and a smaller amount of land that is either suitable or attainable for our purposes. These considerations limit the amount of land that can be acquired and therefore the amount of GST that can ever be in circulation.
