and why you keep saying "free bitcoins" ?) i intentinally wrote few times that i'm not talking about free money. free money leads to greed and lazines. two of the worst burden of human nature. by distribution i mean the widening circle of bitcoin users to the whole Earth population, but defenetly not on the base of foreceble expropriation and equal redistribution. this is way to nowhere.
it has to be some other way: just, transparent, beneficial for everybody, stimulating trust and honesty, fighting greed, corruption and laziness.
If you don't give them for free, it means that they have to either buy them, which is already possible almost everywhere over the world, or work for them, which need some skills and luck, but it's possible too. So I fail to understand what you mean. If you don't give for free, there's no way you can give to everybody, they won't afford it or don't want it.
The bridge you want is, on some extent, made by social-oriented political parties, which in theory give out some minimal money to the poor (and in reality, in most cases, encourage laziness and basically buy votes with public money), in many cases sacrificing a proper development of the country (at least that's what has happened in recent history of my country).
I've noticed that wherever political parties are involved, greed, corruption and laziness are present. We need something worldwide and new (none of the current or past political regimes). But that's "science fiction" again.
But the bridge you want is not necessarily related to bitcoin. Plus that I would give money to people in a currency that doesn't have limited supply and irreversible transactions, since there's always the chance people won't withdraw that money.
I think the important thing is to make sure that people who are capable of working are contributing to society. You could give them free tokens to buy the basic good things they need they can't afford due to lack of money. I'm not sure it's a good idea to give them money to spend most of them on things they don't need. I would probably give them tokens they can only spend on the basic things that's needed for their survival, under the conditions that they will be developing their talents by learning their desired skills from established businesses through apprenticeship. By the way, the established businesses would also be supported (if they are good at what they do) by the right government under the conditions they absorb the apprentices.
An apprentice could easily use his token to buy the basic things he/she needs esp from the businesses the government is supporting. The token can be converted by the businesses to the main society's currency.
I think this would be sustainable and would guarantee the needy their basic income.
