The market element where the game tokens can be traded adds another dimension
That is not another dimension. This is Layer Zero of gaming - the place where you decide winners and losers.
The monetised layer is optional. You can play bridge all day and have the winners/losers identified without a single penny changing hands. There is a gameplay present.
No gameplay means the money layer is essential. Harvesting a tomato does not make you a winner. Everyone else did. If you buy a Farm for 5 Hive and sell it for 0.5 Hive later, you are the loser (unless the timeframe was really long and you mined a shitload with that Farm). If you buy it for 0.5 Hive and later sell for 1 Hive, you are the winner.
If this kind of stuff does not happen on the daily basis you can tell the game is a Ponzi scheme which is going to determine the losers one day pretty easily.
