For those who don't know, earlier in the beta a sandbox feature was used which provided limitless pizza to players. This lead to a lot of discovery and changes in the game. That being said, at this point many abusable aspects of the game have been removed, and testing a more natural growth and development of gameplay feels necessary. I disagree that there is any "expectation" for players to pay for items. You are to some extent provided that option; but by no means required or even advised to take it.
