I agree with all the reasons you suggested.
Looking at the second reason you suggested, I thought robots could contribute greatly to reducing corporate corruption.
As you say, robots use only energy and the company has to pay for that energy, so the company will not overuse it and control the amount of work ‘themselves’
The reason for the conflict between workers and businesses was that the company had all the sovereignty over workers' allowances, and I think the problem would disappear if the company used robots.
