It is a store of value; if you have no value to store you don’t need it.
What is a 1.5Kg Brick now, $140k? Well that is $140k the gubernment can't inflate away. Just think of what 140k of Gold are worth today if purchased when Dollars where exchangeable for Gold.
In case you still can't grasp it then go here and type in 140k...this is $3,057,048.48 in today’s FIAT.
