Same interesting points, i'll try to answer some of them.
As for the gold standard getting dropped:
I think people did not really have a choice, what were they going to do, riot? Even if they would riot, would it have mattered? I don't think so. Also, politicians most likely used a lot of propaganda to pull it of (it's what politicians do).
As for the laptops, you only need a cellphone to use bitcoin, and more people have cell phones than people have bank accounts. Many people who want to buy stuff on the internet simply can't, not because they don't have money (well they don't have a lot of money, but still, they have a few dollars), but because they have no bank account, and can't afford one (note bank accounts are more expensive the less money you have!). Bitcoin might allow them to order things online, if even very small payments like food from a local store or whatever they want to buy.
Many poor people live in countries with huge inflation, if they have to choose between losing 10~30% of their purchasing power guaranteed each month versus owning a volitile (but often increasing) bitcoin, it would be a no-brainer.
Security may be a problem for poor people and technologically challenged people, but for those people there's webwallets (coinkite, coinbase, blockchain), i agree you'd have to trust a 3rd party and they are not as secure as a cold wallet, but hey, it's still better than a bank!
I agree with your assessment of the gold standard. However, it was not until the 60's that they pulled the silver from coinage. Then the early 80's in the US and mid 90's in Canada for copper in pennies (and early 80's for nickel in Canadian nickels.) And still nobody bats an eye. Only a small percentage of people who had been using silver their whole lives as a store of wealth and for it's trading value consider it worth holding onto. the majority were (and are) content to accept that a base metal quarter has the same value as one of silver because they have the same government issues stamp of approval.
If people who lived their lives knowing about gold and silver were willing to accept paper and zinc without question I find it hard to imagine people seeking out bitcoin for any advantage or stability it may offer.
You make an excellent point about the relative cost of banking to the poor. Also the fact that so many countries have insane inflation. BTC may help to protect them as it matures and stabilizes. I do not know how much of an advantage that is if you are already poor and living paycheque to paycheque in these countries.
Continuing with Zimbabwe- they adopted the USD for stability. There would be nothing to prevent them from adopting BTC for stability. However, aid from foreign countries and the stabalizing forces were sent in fiat. There would never be enough BTC flood a countryto stabalize it. The people of Zimbabwe had noting to offer the BTC miners in the first world... the government had nothing to send to us in exchange for BTC. It was an easy matter for countries to print up a bit of paper and send it over to Zimbabwe "on loan." If the entire country is adopting USD to function and I have BTC it still does not help me (I still cannot purchase food, fuel, shelter without widespread adoption.) I
