Think about people like Changpeng Zhao, Conor Mcregor, Donalnd trump, Floyd mayweather, Andrew tate.
This kind of people can survive only if they keep being rich.
If for example they will lose all their wealth and secruity guard and walk alone on the street they can be kidnappep easily.
The only things that keep them alive is money.
Think about this day. People think all the time this carteñ boss made so much money from drugs sales. Why he wouldnt just quit and live with his wealth.
The answer is simple he cant. The moment he give up on his job and his secruity guards he will be prone for kill.
There is a certain point in life that there is no go back and you must continue with your life.
To super-riches like CZ or Trump, money is what keeps them who they are now but I think you misunderstand the meaning of money to them. See, on that high level of wealth, money is a purchasing fiat to buy things or material lifestyle any more, it is more like a power that influences society and countless people around them. Suppose one day they are not that wealthy, high chances are that their lifestyle can be maintained but the rapid loss of power will make them suffer. The real power, which is supported by money acutally, is indeed what keeps them alive.
