I understand your points, but I think what scares people is that the solutions you propose are disregarded by our politicians. At least in the US, both politicians and the large donors funding them seem to be more and more allergic to anything resembling an universal basic income, and they do their best to scare people away with fearmongering about “communism”. The US is also doing a hard U-turn away from environmental protection and is trying to frame environmental conservation as radical and harmful. Other countries might be doing better on these fronts, but it’s definitely not a good sign that the US doesn’t seem to be on board with your first two solutions.

In the more immediate run, I think the concern is that AI will reduce the ability of workers to collectively bargain and thereby grant the wealthy oligarchs even more control over their workers’ lives.

I completely agree that governments and power brokers will disregard these solutions unless forced.

However, they will also disregard any attempt to slow down or halt AI progress in general, so it isn't like the people wanting to end AI in general are any more likely to succeed than those wanting to do what I propose.

I personally feel my suggestions would be slightly more feasible to gain support for than trying to stop AI completely. The power brokers in control of AI currently certainly aren't going to stop developing and pushing AI, but they might be convinced that sharing the wealth is the only way to avoid massive revolt in the long run. While it is conceivable that the wealthy wouldn't need the masses for labor like they do now in the AI future, they still need to not be killed in a massive uprising when 90% of the population is unemployed and starving. While I know a lot of people think the plan is just to kill off that part of the population, that is not that easy to do even with an army of AI robots, and would likely be cheaper and easier to just share a bit of the productivity. I don't think it will be trivial, but I don't think it is impossible.

UBI has been a major donor priority, at least on the left.
