I agree - PLEX works in EVE as it allows more players to stay subscribed. Essentially the seller is employing the buyer for time in return for ISK.
Ryzom adds difficulties because, even if the proposed game time is traded for grind or supreme mats, there is no real way to gauge the value. In EVE, a buyer or seller can get a price check in contracts, market in Jita 4-4, or various aggregator websites to get a rough idea of how much a PLEX is worth at the time.
Ryzom does not have any equivalents to those and, without them, is sure to leave a sour taste as someone, somewhere got a better deal.
