While Bitcoin promotes mistrust and decentralization, true to the hacker ethic (
Hacker ethic). Ripple is a currency based on debt that promotes trust. One of the origins of slavery in human history is debt and trust. Debt also takes away your dignity, while you owe someone something you are not free. Unless you are a scammer and don't acknowledge the debt (but even that doesn't keep you free if the debt is enforced). By trusting someone you are always placing yourself beneath them. Someone who has honest intentions doesn't require trust.
while I agree with you on some of your points, I really have issue with what you said about trust.
without trust, astronauts couldn't reach the moon, air travel would never be possible, no one would drive on the highway, I'll not eat food bought from grocery stores -- the whole modern society is based on trust.
Let's face it, humans are social animals, social animals, be it a troop of monkeys or a pack of wolves, they rely on trust to survive.
Of course blind trust can be abused and lead to all sort of issues, but blaming the evil of enslavement on trust doesn't make sense, it's greed, hunger for power.
