But, is a market really viable in a society where machines can make a surplus of a lot of stuff? is it possible to have a market when most jobs are just automated and most people simply "aren't needed"?
Well i'll tell you something, im not sure about it... and im a proposal for free market myself, but I think at some point in the future, it will make no sense. Maybe in 100, 1000 years, I don't care, it will eventually make no sense.
Yes because trading will always exist, and has always existed, since the beginning of the universe.
When you inhale air you trade your CO2 to the plants, and the plants give in return O2.
Not all trades are commercial, but trading will always be present. And for a trade you will always need a market, so the best and most efficient form is a free market, not a controlled zombie market.
Otherwise lets put trading tariffs and regulations on the plants O2 trade, and lets make the plants pay income tax

Trust me free market in its core will always be needed, even in the soviet union you could trade basic things, you just couldnt had means of productions. Imagine if you could have, people would live better.
Controlled market VS Free market is like a disabled wheelchair person vs a marathon runner athlete, you just cant compare the two.
