- run for office
- build a career in monetary policy
- join a campaign
- start a non profit advocacy group
- lobby my representatives
These only have any effect (if they're even possible otherwise) because we're a democracy with elections. Can I personally change the supply of USD? No, but that's because that kind of change affects the entire world, and there should be a serious process around it. But my point is that there _is_ a process, rooted in (if imperfectly) the fundamental liberal democratic belief in humankind's right to self- governance.
Facebook has no such guarantees. It's a serious threat to those principles. There's a huge difference.
1. Build a competing product (social network, cryptocurrency, etc).
2. Build a career at FB, to influence from within.
3. Join/start a campaign against/for Facebook to influence its (potential) users.
4. Lobby your representatives to change whatever you don’t like about FB.
Maybe you have a point but so far it’s not very clear :)

Everything on your list is only possible because we live in a free society with representation and authority over corporations. If we start ceding more and more core governing functions to corporations, how long do you think it will be legal to build a competing product? How long do you think you'll be able to lobby your representatives? How long do you think you'll have the right to start a PR campaign against Facebook? Look at your favorite authoritarian regimes for the answers.
But if Libra starts challenging the USD even just in the US, let alone in the rest of the world, suddenly there are two dials to turn: one for USD and one for Libra. As more value is held in Libra rather than USD, US monetary policy becomes less effective.
And this is just the money supply issue. Others have raised all kinds of issues about fiduciary duties, privacy, regulation, confiscation, security, and so on. While I wouldn't at all argue that the US approach to these issues is perfect (far from it), there are at least some laws and so on. Nothing would prevent Facebook from freezing your wallet, or freezing your account, or banning you from their platform, or tracking metadata on your purchases. I would also assume (perhaps incorrectly?) that law enforcement doesn't have to jump through the same hoops to get your payment/account information, so there's potentially more loss of rights there.
This is exactly what Facebook's vision for Libra is: an alternative currency to the USD shared internationally and controlled by their consortium. They say it will be pinned to the USD and other stable currencies, but there's nothing holding them to this (and in fact most cryptocurrencies play with this). I deeply believe allowing this to happen would be a grave mistake for all of us.
I live and vote in US and as soon as the majority of US residents decide to vote contrary to my wishes I have to accept the authority of whoever they elect.
Frankly I don’t see much difference.
