The latter part is true, but BTC cannot provide that. It's nothing more than a nifty hack. It kind of works, which is impressive, but it is horrible inefficient and impossible to scale due to its inherent limitations. So far the only solutions that have been proposed were to tack on even more complexity. To make matters worse, all of these solutions have remained vapourware for quite some time.

How? It would have not prevented the Dotcom Bubble. It would have not prevented the Subprime Mortgage Crisis. It would have not kept Argentina or Greece from borrowing way too much money. It's a libertarian pipe dream that Bitcoin will magically solve all of the world's economic problems. In fact, it would make matters worse due to unpredictable volatility and its lack of scalability. It would only drag any country trying to adopt it into a deflationary death spiral. There is a reason why the gold standard has been abolished.
