OK so I was bored because I have to explain the background a bit, unis in Greece are all public and there's a lot of leftist organizing going on there (also how I got organized). Anyways one of the leftist orgs doing the organizing is KKE, the Communist Party of Greece, which is one of the largest and most powerful ML parties in Europe (if not the largest), one of the few that participate in parliament. However they're old guard commies with an aging voter base so they're pretty bad on some stuff (for instance they're little better than a conservative party on LGBT+ issues since their older members mostly adhere to the "bourgeois decadence" doctrine, and they also sometimes take positions more moderate than they should on some stuff, although to their credit they do tons of militant workplace organizing, which will however stop being the case if they keep refusing to stop being boomers and start being more open to working with other leftist orgs without trying to appropriate them).

A few years ago there was this dude in my uni who was recently organized to KKE and he was trying to explain socialism to some kids he was trying to recruit, but he was a noob so he didn't really know what he was talking about yet. So he started talking about the final stage of communism (which is kind of a dumb thing to bring up to people at first, but I guess it's better than trying to redpill people on Stalin which is what his older comrades tried to do to me the first time they talked to me lol), and someone asked "so if there is no money, how does stuff move around?". The dude started explaining that "well, you don't need money, you could have, for instance, potatoes. So maybe you have a toaster, and I need your toaster, so I give you 50 potatoes for the toaster". The result was that the conversation ended up being about a potato based communist economy, it was pretty funny before some other organizer came in to steer the conversation back into something sane again.
