The economic system is not set in stone. If everyone is irrelevant to it, the economic system becomes irrelevant to everyone, and a parallel system gradually replaces it.

IMO we've had the EXACT same economic system since we were living in caves, it's called "supply and demand".

What do you do when "demand" for human labour drops to zero and "supply" stays at >8 billion.

No account of tinkering at the edges is going to fix that. We're in a much deeper fundamental problem than you might seem to think we are.

Sadly "earning a living" goes beyond economy, it is also deeply involved in societal and cultural values.

It really isn't. Just 100 years ago "earning a living" meant growing food themselves on fields behind the house for the majority of humans.
