The gold supply is inflating at about the same rate as bitcoin right now, but has enough incoming cash flows to keep the priced propped up enough to maintain a $10 trillion market cap. Obviously some of that incoming cash flow is for actually generative industrial use cases, but it's a minority, https://www.statista.com/statistics/299609/gold-demand-by-in.... The lion's share of incoming money flow is for jewelry, long term savings/investment, and central bank holdings, and you could argue that most of the jewelry use case only exists because it's a good store of value, since we can easily make jewelry that looks as pretty for much cheaper than the real thing.
So, since most of the cashflows into gold are just people holding long term with the expectation that there will still be people wanting to buy it for investment purposes in the future, and this scheme has worked incredibly well for 5000 years, why couldn't the same be true of bitcoin?
