The true wealth is something wich you have control over yourself not the third partie trust.
The only proof instead of trust will work.
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.
Land and property not good because you can not take it with you or move from another place to another in some case the car would be even better asset to have.
That's not how this works.
Let's start with the fact that you have no control over fiat money. At least not any more than you have over a piece of land.
You think you can't move land when you travel? They will take your money as well, just like they did to Ukrainians fleeing to the EU and as the Chinese did to people who wanted to leave the country.
Fiat money is only a transactional token. It doesn't belong to you any more than your apartment.
