I’d put it on a spectrum, with most of my wealth I am like you said growing wealth through productive assets like stocks, but that doesn’t mean you can’t decide to hold some portion of your wealth in something outside the system. Some sort of insurance policy if you will. While having all of your wealth stored at various counterparties (your bank, broker, etc) will likely work out 99% of the time. There is always that minuscule chance that something happens, maybe your account gets hacked and drained, maybe some new government comes into power that decides to confiscate 10% of all wealth for some emergency situation, maybe a socialist government gets into power and decides to levy all kinds of new taxes/levy’s on people with large account balances. Unlikely yes, but in that circumstance it would be quite nice to have some portion of your wealth in an asset that they can’t confiscate, could be taken across borders simply through a plane flight, or could be sent to any person globally at the click of a mouse.
