Yeah, some folks perceive the government crackdown case as "nothing", but clearly that could still be a $1000+ valuation scenario simply through underground usage, a massively profitable "all" for anyone holding coins today. At least in my mind, "nothing" excusively means that technical or feature problems drive Bitcoin to zero
marketshare among cryptocurrencies, since clearly at least one cryptocurrency will forever be necessary. The cryptocurrency concept is just too useful and is here to stay, whether it's Bitcoins or some 2nd generation coin.
To that point, someone in the thread you referenced, mentioned something tremendously insightful that might be easily overlooked, and which is yet another fantastic selling point for Bitcoin: in countries with highly regulated medical environments (e.g. UK NHS, USA Obamacare/FDA), Bitcoins are a kind of
medical insurance. Silk Road gets lots of negative press, but not all illegal drugs and treatments are recreational; it's completely conceivable that someday you or I might have a disease or condition whose treatment is not available through legal channels, either due to an experimental nature, price controls, or ideological issues.
Regular insurance won't cover you if you desperately need to buy "illegal" medical goods and services. What can you buy today, that will give you access to black market medications and treatments tomorrow? Answer: Bitcoin. The following bullet points sound like humorous hyperbole, but can be made with a straight face:
- Do you live in the USA or European nanny state? Bitcoins are an essential part of a medical insurance portfolio.
- Having Bitcoins might save your life.
- Not having Bitcoins might be hazardous to your health.
