With human's greed, I don't know if that is possible. As more advancements are found, humans will want or maybe NEED to have that immediately. Maybe it's a cure to new sickness, or something with very limited supply. There will always be those that can get to it first. Whether it is a ticketing system or lottery. Depending on the necessity, people can kill for them. I think the only time we will have a post money scenario, is if we have a fully functional metaverse, and people are just brains inside a liquid.
