Every good revolutionary knows that he or she must provide something to the people that the status quo does not provide. Manhattan bars do not need Bitcoin. Big, domestic retailers do not need Bitcoin. (Don't trot out the 'no chargebacks' argument. We tried that. It didn't work.)
We don't need Wal-Mart to accept Bitcoin. We have
Gyft for that.
What we need is more remittance networks to major cities in the Developing World and more small-scale import/export.
I think this basically hits the nail in the head. I think the success of bitcoin will be a large part depend on what will hopefully become a hindsight 15-20 years from now, just like the internet itself was in 1992.
The fact is crowdsourced content generation and social media, the main new internet trends in the past 10 years, have propelled many new companies formed recently to be smaller and more agile. What's more important is that these organizations can operate anywhere in the world, and many don't even physically need to be in the same place. Adding to this are the globalization trends led by developing economies such as China, India, those in South America, and many more. Having lived in several countries the past few years of various economic developments and political stability, I found it amazing that more and more people are speaking the same language by ways of the internet, regardless of religious, political, or economic backgrounds.
Furthermore, trades between smaller merchants and consumers that made the likes of eBay, Paypal, Alibaba, and to some extent Amazon so popular today are seeing great demands for internationalization. We are even seeing the interesting reverse trends of manufacturing heading back to fully developed countries like the US, perhaps because latest technologies have enabled manufacturing costs to go down, and also we are seeing the trends of greater international demands for US/European produced goods, because people internationally now can afford higher quality goods or even vanity products.
In summary, there is an ever-increasing demand for a platform that can be used to conduct trades globally at a smaller scale, basically in a c2c fashion. A decentralized currency like bitcoin is a great foundation to the payment facilitation piece of this puzzle, and it can build upon the foundation laid by c2c eCommerce platforms like eBay and the rising crowd-based brand advocacy made possible by social media.
That said, It's not an easy road though and require a lot of effort by the community to continue to pour significant energy and investment in strengthening the infrastructure and integration points, and perhaps a few "killer apps" along the way to speed up adoption. But from that standpoint, it does look like it's heading towards the right directions.
