> But could you make a better game if you didn't need to funnel people into buying gems at all? The answer is always yes - you always need to give up something to make people buy gems.

This ignores the fact there aren't unlimited resources to develop and maintain a game. Not requiring people to buy gems would improve some areas of the game for sure, but making less money is certain to impact other areas of the game - you always need to give up something in order to fit things in budget.
