assuming that rich people like bill gates, jeff bezos, mark zuckerberg, ect... decided to put some of their money like 2-3 billion usd by storing such money in shopping malls, luxury hotels, ect.... instead of offshore bank accounts, but then how could they actually use that money vs accessing it via offshore bank debit card when they wanted to make a purchase like a brand new car, a small residential home, levis online order purchase, purchase lacoste polo shirts at their boutique, ect...? lets say 1.8 billion usd approximately, why would they be better off storing such money in luxury houses, luxury cars, actual gold, precious artwork, gems, ect... rather than have the money deposited in some offshore bank where such money could be accessed like your average joe with a bank debit card? even if such money is stored in such luxury items or places, how can they use it if its already stored in there then? this part i dont fully understand. how could the money be used like cash if already stored in such places and items?
