The fake wealth: land, property,money in bank,stocks,bonds.
The true wealth: food in your home, paper Fiat currency money in your hands the pyhsical gold and Silver and cryptocurrency in your self custody wallet.

We read as childhood..
If knowledge is confined to books without acquiring knowledge, that knowledge is of no use when it is needed.

If your wealth is controlled by a bank or some other third party then the last wealth will not be of use to you in your need.
In our country, when there is a sudden flood or any other natural disaster, the only time of need is the money and food collected at home. The money saved in the bank is not useful in times of dire need but requires the permission of various third parties to withdraw that money.
