I just mean that people in a post-capitalist society will still need to convince each other to use their limited time on earth to give their production the time of day. For example, artists are still gonna have to market their songs to get people to listen, even if the motive for it is different (not profit, but notoriety or being accepted as an artist for their contribution to society). If I make a new design for a train wheel, I still gotta convince people it’s worth their time to even analyze it for improvements. Even without profit, we will probably have people who think they found/made a good thing when it’s actually shit. Making a filter for time wasted means some convincing of others is necessary
