The primary purview of the state is geography (borders) and taxation (monetary policy). Allowing foreign money to be the primary medium of exchange directly challenges monetary policy.
Who said anything about a primary medium of exchange? Should dollars be disallowed as well? How about bitcoin? Starbucks gift cards?
It's not going to be a very amicable discussion.
2. No. I don't think its available yet. Its not really meant to be a speculative investment since it's backed by a basket of stable currencies. Although it may be like a closed-end mutual fund where the investment could trade below or above net asset value. But I wouldn't recommend speculating on some price increase even if it takes off
3. No, I'm just interest in cryptocurrencies read the white paper [0]. I suggest you do the same. It's pretty interesting. I do have a fair bit of free time though
Their blockchain neither has block nor chain as I seem to recall. If the company is already lying in their whitepaper, what exactly are you expecting from the real thing?
Doesn't mean its (always) sensible to accuse people you disagree with of course.
Monetary policy is entirely about currency control for inflation, etc.
There are also small countries that are pegged to the US dollar.
When you are a small-potatoes nation-state, and have a non-diversified or small economy, it is a great idea to use a larger, better established, currency.
* It's more stable * Trade is easier * More than 3 banks accept your currency!
The incentives of the nations controlling the euro are well known to Montenegro, and they trust that those countries will keep the euro stable.
Libra is a whole different ball of wax. It's not just a currency. When you use it, you are tied to Facebook's terms of services, Facebook's desires, and Facebook's fate. Your individual citizens could be locked out of the economy for reasons that have nothing to do with your nation's laws.
If Google and Apple wouldn't agree to use Facebook-dollars for all their transactions, I don't see why a company would agree to.
There's a big difference between having a currency pegged to another, and not actually having a currency at all, and using physical foreign currency for everyday transactions.
Pegs can be broken and may be hedged with FX futures.
The second situation is a much stronger existential commitment, which makes it more reliable and predictable. Reinventing a new national currency is a high barrier, which cannot be hedged directly in the FX markets (although sovereign CDS might be close enough).
Not sure what you’re trying to get at.
