This list of ideas will be of great benefit to all! (vote for @fyrst-witness !!)
Your concerns about basic income are valid, but there is an additional dimension to dan's idea that would very effectively mitigate the 'population of welfare bums' problem. You see, those people who get handouts, 'know' they are getting handouts - they know they are a drain on the system, and that the system is not designed to sustain them. This causes a psychological/motivational problem, where the individual begins to identify themselves as a worthless beggar, and their behavior follows accordingly.
Dan proposes fair distribution of the spoils of a successful economy, which would motivate people to participate, rather than causing them to identify as bloodsucking outsiders, which leads them to becoming exactly that.
It's very interesting!
