I don't want to attack your good faith in humanity, so I will ask another way - if a system was reliant on workers, what reason would there be for those workers to exist , after their work became automated?
We just need a new model for existing that isn’t based on labor. We should have started working on these problems in 2016 when it was obvious they were coming, but we elected a regressive twice to help us go backwards instead.
What make life worth living? Is it love? Is it beauty? Is it the sense of having agency?
Sadly, we are not smart enough to know until it is taken away.....
Let’s build abundance first and solve inequality later. Instead people are keen to prevent abundance and keep everyone level by keeping everyone poor.
If you've ever been laid off or fired, you might have noticed that you don't cease to exist when your contract ends.
Think just a little past the most direct consequence - let me rephrase GP's question: What reason would the ownership class have to provide these necessities to workers when they no longer require their work?
Obviously, nobody is going to blip out of existence when their layoff notice is signed, everyone knows this and nobody claimed that. If you stepped down from your philosophical post humanist highchair a bit, you would realize that.
