....since the goal for Ember is to more-or-less cover the general ideas expressed in number 2 I'd like to think you should be rather pleased with the planned economic model as it comes to be.
I think this leads to two important questions.
1: Has a "crafter driven economy" been announced as one of the design goals?
2: If so, would the continuous crafting of various destroyable call downs and buildings potentially fulfill that need?
In addition to the crafting of gear and weaponry that won't break....
Expect to see the resources used in the creation and replacing of the various call downs and buildings that can and will be destroyed.
