Saying something is “pegged” is saying that the price is fixed. There doesn’t exist any volatility between pegged instruments because that’s what a peg means.
So you have to compare them to other things, which is what inflation (or deflation) measures. And gold pegged usd has volatility to other items in the economy greater than modern fiat usd.
Then I certainly feel confused & may be wrong.

Edit:
You're near-certainly right that pegging in dollars would means some rate, let's for simplicity presume a constant ratio, between dollars and what it's begged to.
I think crux is what happens if we model two different currencies, one of which is begged, and the price of te commodity in each.
If after the conversion rate you can get cheap gold, that keeps golds value low and pegged currency's value high, I would guess.
Again I think restricting impots in the commodity is necessary to maintain supply.
It might even be the smart move. depending on the good Samaritan protections in your jurisdiction, you might be open to liability if you try to help.
The parent comment would still be correct though, and billionaires are just filling a power vacuum, nothing wrong about that. I genuinely believe U.S. is also just filling the power vacuum & mostly has done nothing wrong, similar to other superpowers. There's nothing inherently wrong about letting the child drown unless you are the child & can protest about your own drowning, and there's nothing wrong with filling the power vacuum, because the universe has determined that someone ought to do it sooner or later. And we cannot do anything about this.
I define problem/issue/similar words in the following way: a thing that, if deemed existent by me, is also my own fault & realistically fixable by my self.
