> The white paper explicitly gives the Libra Association (i.e. Facebook and its partner validators) governance control over the cryptocurrency.
> Here's an easy scenario to imagine that shows how incentives would get misaligned: Facebook and the other validating nodes of Libra are financially compensated by interest from the collateral for Libra tokens. If Libra is successful in its mission, it will become a global currency that's stronger than the assets that underly its collateral.
> When this happens, suddenly Libra being a collateralized stablecoin stops making sense. Kind of like when the US Dollar no longer needed to be backed by gold since it was a strong enough currency/unit of financial measurement on its own. The US then got rid of the gold standard and has since saved itself untold money in custodial expenses they would have been paying to hold all that gold.
> The Association would never do this for the Libra however since it is literally how they are funding their own operation. Even if it's in the best interest of all Libra users, the centralized governance association with all of the authority to make this improvement would choose not to because it's not in their best interest to do so.
> There's no leap of imagination there - it's just how power and incentives work.
Your basing this argument on the fractional reserve monetary policy that the libra association is hedging against. I believe we are moving towards a world in which global currencies become the norm. There will be 2 types of global currencies, corporate currencies and decentralized currencies, aka Libra and Bitcoin.
Both forms will have to have a mechanism that prevents inflation, Libra will do that by being fully backed, Bitcoin does that through Nakamoto consensus.
With digital currencies it becomes possible to move your entire "cash" holdings in a matter of minutes, so a fixed supply currency like Bitcoin insures that Libra will never dilute it's supply because the barrier to exit the currency is so low. In democratic countries like the US the mechanic that prevents massive inflation is mostly voters' influence over the federal reserve. Of course it isn't perfect the dollar has been inflated ~300% since leaving the gold standard. With corporate global currencies we don't have such voting powers.
