The size of $500 worth of gold - about 3.5g - is a small coin or a thin gold ring.
(Thinking of it, it’s actually funny that we’re back to the times of being able to buy a house with a bag of gold coins)
Regular people definitelly buy gold in physical form because it’s such a concentrated form of storing wealth, though in the West this was a lot more common in the old days and currently is a lot more common in countries like China and India.
Oh, and if you buy gold certificates and the certificate issuer goes bankrupt (like so many companies go during Economic Crashes and Depressions), then in the eyes of the law that gold is not yours and you’re just another creditor of the assets of that company, so forget all about getting most of the value of that gold back: you might want to reconsider gold certificates for value safe-keeping outside of the dollar in case of a major economic crash in the US since if the gold isn’t actually in a legal structure were you own it (i.e. you legally have direct ownership of a chunk of gold and pay somebody to store it or store it yourself), you remain totally exposed to whatever economic upheavals happen where that company is based.


Well, it depends really: companies whose operations are mostly outside the US whilst being listed in USD in US stockmarkets will see their stockprice go up in dollars is there’s a run on the dollar, not because their value went up but because each dollar is worth less.
So such stocks will actually hold a lot more of their value than it would if that money was held directly in dollars.
PS: I actually have a “funny” Brexit story around this - back when the Leave Referendum won Brexiters (the British MAGA, and as equally well informed as the American version) were celebrating how the UK stockmarket indices went up in value with the Leave Referendum result of Leave. However those indices were only up in pounds and down if quoted in any other currency than the British Pound, because what had happened was that the pound tanked about 20% following the Referendum result so naturaly values for companies with extensive international operations translated to more money in british pounds.
