Achilles made a very good point. The US government will never allow such a system to get popular. As long as it is a novelty, they let it exist.
Another fun thing. Here is a pro-bitcoin site, trying to disprove myths about bitcoin. The funny part is that about half of the myths are actually true:
https://en.bitcoin.it/wiki/Myths
For example:
Myth: Bitcoins are worthless because they aren't backed by anything.
Response: Gold isn't backed by anything either.
Well, first, gold has an intrinsic value itself, being a valuable industrial metal for practical usage or as a jewelry item. Second, this is not a valid argument, just an invalid comparison.
Here is another one:
Myth: Anyone with enough computing power can take over the network.
Response: CONFIRMED,
Well, a confirmed myth is also known as FACT.
Here is one talking about what Achilles brought up:
Myth: Bitcoin violates governmental regulations.
Response:There is no known governamental regulation which disallows the use of Bitcoin.
This is simply not true, and the myth is again, true and a fact...
Myth:After 21 million coins are mined, no one will generate new blocks
Response: blah-blah-blah
The response doesn't deal with the question and the myth is again, factually correct.
Myth:Quantum computers would break Bitcoin's security
Response: Yes, but...
But, but, but if it is a yes, then it is not a myth.
