Maybe we have a different look on basic income, for me it's like unemployment money with less steps and less overhead (less bureaucrats). I also dont know why you pull in marxism, but those systems normally starve because of bureaucrats (hello germany) where you have to fill out 10 papers to create one praline, and NO i dont say germany is "marxist", but they are really good at always taking the worst from both sides.
For giggles, lets say every work can be done by robots, every service by ai and energy is free (dyson sphere or whatever you want), who's left to spend money and for what? And tadaa StarTrek ;)
If all work is done by robots we have much bigger challenges than who spends money. We need to consider how to counter dynamics and incentives that might favor having fewer humans dependent on the system, for example. We also need to consider how we avoid either humans losing control entirely or human control being massively centralized to a small group of people running everything.
I'm also not sure why you assume I haven't read up on this topic. We may disagree, but its extremely dismissive to assume your view is right and I must simply be uninformed.
I get you don't like marxism. But you come off like a parody when you have such shallow grasp on what it is. Most real life communist countries, it is a crime to be without work. As far as you can come from a basic income.
Continue to avoid exploring obvious solutions because certain words have been made into epithets, or failed previously because they were solving future (now imminent) problems?
If we have a system depending on trading our labor for money to pay for stuff, and the value of our labor goes to zero, we need a different system.
We can't paper over that fundamental crack by giving governments even more power to decide what every person "needs" and send out resources accordingly.
There are so many problems in that system. How do we actually decide prices when every consumer has the same base level of money to spend? How does the government decide what we all need or deserve? How do we avoid the corruption taking over that massive power granted to dole out resources? Are we just living in a feudal state again? Does the government need to control the means of production to keep such a system stable?
