"defended the integrity" - not really.
The comparison with some far left stuff was to do with a situation happening following a military coup or revolution - what was then labelled as tabla rasa or fantasy.
Sure the OP is speculative. Sure the idea of a military coup is also speculative. It doesn't really matter either way. We can still discuss what the outcome of a certain voting system is - for example you could set up a voting system in a small voluntary group of people and see how they behaved. I think it would tend towards equality. We can also discuss the theoretical situation that somehow this system was established and enforced and what the outcome of the voting would be.
I understand that people are objecting that it could never happen in the real world 'because capitalism' (<<-- note inverted commas not quotations marks), and if they don't want to discuss this because it is "silly" (<<--note quotation marks) then fine, they can stop discussing it.
