This is a brilliant article. I am not completely comfortable with Basic Income, but there haven't been other solutions that really address the problems society will soon be facing (with continued efficiency and technological progress pressuring the labor market). You have re-envisioned the problem and presented a new way of addressing it.
I still am not convinced that the system you describe could prevent someone from selling or trading his/her stake in the means of production, since at some point, I think the proverbial ATM machine allocating benefits still must spit out something valuable that could be taken/exchanged/bartered (money, resources, food). The stake may remain, but how could you prevent someone from exchanging anything that's produced from it?
Maybe there are ways. I will continue thinking about it. You've provided some good food for thought.
