Now you improve strategie, because all money must be get by "goods" and the market place. What do you think about that??
In my opinion you do not improve strategy, you are reducing strategy, because you eliminate one or two strategies from the game. The red mosque tile is one valid strategy to win the game, but you make the red mosque tile worthless. That means there will be more competition for goods, and that also means that more players have to expand there handbarrows. And it means that players will no longer go for the ruby of the small mosque.
Conclusion: Your version makes the game unbalanced.
