The practical implications of a decentralized trustless system could disrupt so many industries, freeing up so much capital for those who need it most. This is the true era of the internet and I particularly liked your point about bringing together the human family, through this technology we may eventually be able to dissolve the boundaries between us (though I suspect this could take generations)
I think my favourite disruption potential is online identity and voting, allowing the masses the ease of use in participating in their democracies will allow true freedom to flourish and dismantle unnecessary bureaucracy. Like and Resteemed :)
