Gold is actually really good at transferring and measuring value. Think about what a "good" measure of value would be have. It needs to last over time, not corrode or dissolve to the forces. It needs to be distributable, Divisible.. to be ubiquitous. Hard to create/refine, hard to find, so supply can't easily be inflated. It doesn't matter what the object that is being used for exchange of value or holding value, tha…
Hold on - you say "we find more gold every day" and then go on to suggest that the money supply doesn't actually need to keep up with economic growth? If we had the technology to maintain 0% inflation, we would do that. We can't, and rather than risk deflation we instead target low positive inflation. This is because deflation leads to nightmare spirals where people start stuffing money into their mattresses instead…
I don't think this is quite right. My understanding is that a low positive inflation would be targeted anyway, because it stimulates the velocity of money; i.e. there's a downside to hoarding, since you need to beat inflation to come out on top. So people will be willing to invest to at least some extent in risk assets, or to buy things now rather than later.
Which, yes, makes inflationary spirals possible, but they've proven less damaging. The inflation numbers seen in regimes that actually collapsed as a result are absolutely dizzying; whereas the deflation seen in the Great Depression was... significant, but not nearly comparable.
