Unless someone can come up with an argument showing how this time will be different (hint: it probably won't), then this is just a rehash of an old argument.
It should be fairly apparent that technology and computational power have advanced in such a way that the capabilities of current and future types of automation will become more extensively applicable than past types. If they weren't more applicable, then we wouldn't be having this conversation..at all, as the types of automation wouldn't be changing.
We might not even need sub-minimum wage agricultural workers any more because we can rig up image sensors to robotic arms which can determine what is a weed and what is a product. We might not even need burger flippers because we can set up IR surface sensors to a device that will flip an automatically pressed, uniform burger patty at the perfect time to create a brave new world of monotonous sandwiches...and to top it off, we might not even need coders to write any of the software that all of this world runs on.
The idea that a world where widespread, digitally controlled automation should even think to hang on to some of these basic ideas of economics you reference seem to be in question. The idea of what is considered employed vs. unemployed will shift dramatically (e.g. does subsistence farming count as a job? and so forth). The variables we use to value currency will be called into question.
in economics, just like in biology, when the genetic pool gets too small for a species, the result eventually becomes extinction.
I agree with you here, though I would go a step more in the direction of the fundamental: in this case, when the pool gets too small for the convenient metaphor of monetary systems, then the value of monetary systems will disappear.
