You don't have to put all your eggs in one basket. You could accept payment in dollars and bitcoins, and exchange the bitcoins for dollars the day you receive it. If the bitcoin market suddenly crashes, you'd only lose the amount you hadn't managed to exchange for dollars.
And how exactly would you exchange bitcoin for dollars? Presumably, you'd have to go through a bank, or PayPal, or a regulated brokerage house of some kind. To keep bitcoin from taking off, all the US government would have to do is pass a law or put pressure on the financial industry to not allow that exchange.
That's a valid strategy, and one the US government may even employ. However, other countries would have to agree to similar restrictions, otherwise you could trade dollars for euros, then euros for bitcoins. It also wouldn't prevent over-the-counter exchanges between individuals.
The US government would also run into opposition from groups like the EFF, and I think it would be difficult to word the law to ban bitcoins specifically, and not other similar mathematical activities (like issuing SSL certificates).
That's completely unrealistic. There is very tight cooperation between the major currency blocks when it comes to the crackdown on anonymous payments and on everything anonymous for that matter.
No there isn't. Anonymous paper money is still used in every country in the world, anonymising P2P networks like Tor and I2P have not been outlawed, you can buy pre-paid VISAs and pre-paid phones legally and anonymously and many people send routinely anonymous donations to political organisations.

I thought legislation had been passed stating that purveyors of pre-paid debit cards and cell phones had to ask for ID and keep records so that, if the cards or phones were used in a crime, the purchaser could be traced. I do know that legislation to that effect was introduced. I'm not sure if it was ratified, but even if anonymous cards and phones are legal now, I have no confidence that they will continue to be legal for the foreseeable future.
I don't believe it was. At least, when I was in the states a few weeks back, I wasn't asked for ID when I bought a cheap pre-paid cell phone.
There is a tendency to be pessimistic about the place of anonymity in the future, but I prefer to look on the bright side. The US government doesn't win every fight it enters, and there is a long-term trend toward more freedom and openness, rather than the opposite way around.
Some things are still possible for now. Others were banned internationally (e.g anonymous savings accounts) by exerting great pressure on countries that had these things. I think the direction is clear. My prediction is that in 10 years we will not be able to even connect to the internet without authentication.
You can send bitcoins directly to a person's account without going through an intermediary, such as Paypal or a bank. This means that it would potentially be cheaper, but more importantly it would be easier to automate, and easier to start up interesting financial web apps.
I can already do free transfers to anyone's bank account: it's called BACS, every UK bank account supports sending and receiving BACS transfers, the vast majority through a web interface. Takes 3 days, but who cares?
You can do it faster if you're willing to pay a fee, whether that's to Paypal, or to do a CHAPS transfer. If the point is avoiding paying to move cash around, it's already perfectly do-able.
I'd imagine there's more scope for competition. Setting up a new credit card takes a lot of money, whilst exchanging dollars for bitcoins is essentially free (so long as you have enough bitcoins).
That said, I don't think this is the most interesting part of bitcoins.
