Although you seem well intended, your views are unrealistic.
A world where you can buy anything using Bitcoin, from coffees to yatchs.
Do you know anybody that would accept to stay at least 20 minutes (and up to 3 days) in line to wait for his payment to get accepted and go home from the grocery store?
A world where you can get all the privacy you want.
Bitcoin is not as anonymous as many would think nor would like.
A world without banks.
A world without old currencies, that only create inflation.
A world where you pay only the taxes you wanna pay and not what you are forced to pay.
Governments will resist badly against these. They're goals very hard to achieve.
And you know that if you will not pay takes you'll need to pay for school, road access, and so on, even get your personal bodyguards since there will be no police (no funds).
Yes, Bitcoin is a very good way to transfer money between countries, evade taxation (although this will not last much longer), experiment a revolutionary way to see money / asset / value and public data storage. but most of the benefits you written about don't apply. Sorry.
And you forget the human greed. Anything that holds value attracts dreamers and speculators.
