Good arithmetic here, but: There is a reason the welthy, and most other people for that part, have little money and lots of stuff. The reason is the inflation. What you call appreciating assets, is mostly inflation-safe assets. With sound money it is different, you don't have to panic buy these assets, therefore the demand for sound money might be higher than for fiat money, supporting a higher money value.

That said entities that hold lots of coins are not powerful by means of the number of coins they hold.  Bitcoons in a wallet have no real value until they are traded for something tangible.
