Despite what most of the U.S. thinks, it is entirely possible to get things done without the governments help. But I would also note, that the government has been brutal to people printing alternative currencies in the past. So I should think as bitcoin gets more and more popular, the government will likely take large-scale action against it eventually.
I think i understand Ron Paul's position on crypto-currencies, and even Digital Gold Currencies; as most gold/silver money people, his conviction is that metal "is only real if one can hold it in one's hand..."
It's a pain to shop online with that kind of gold though. So, with that in mind, what perplexes me is why the gold/silver community including Dr. Paul has not widely supported DGC's (Pecunix/Vouchersafe, eDinar) for online shopping with metal.
We can't speak for other people but one thing I saw was that Ron Paul definitely wanted to encourage was the idea of competing companies, I don't think he or any other person who supports gold/silver is necessarily completely against the idea of non-gold/silver backed currencies it's just that historically gold and silver have proven to be the most reliable for tons of reasons that have been argued about to death by anyone who knows about this sort of thing. My own view is I'd say as long as Bitcoin remains open source and it follows mathematics instead of the will of a particular party it may well prove to be a better alternative to gold/silver but we're going to have to see it in action before any conclusion can be made.
One thing I will say though, this is definitely the end for paper currency, I'm sure there are people who will stay in denial to the end, just like with all other empires that decided to collapse eventually.
