Don't underestimate the power of technology in this day and age. Innovative technology and the internet will make sure that if something is as good as it says, people will learn about it really quick.
Compare it to the internet adoption, took 20-30 years til we started using it properly, now with the help of the internet the same could be done with bitcoins, just so much faster. The only distractions at the moment are laws and the government. But that will clear itself out soon anyway.
You are right about technology, but bitcoin isn't just technology but wealth and power as well, and we shouldn't underestimate greed and hunger for power on the government/bankster side. Those guys doesn't like things what they can't control.
