I would prefer for the world to be permanent, but the current game design does not allow it. Game has two problems that must be solved before going on to more permanent world.
1. Resources are finite. What will you do when there is no more high Q metal? You cannot will it into existence, there isn't a way how we as players can circumvent this problem. At least not for now.
2. No real end game. You guessed it boys and galls, it's the quality grind. Quality for most things has a cap. Whether its easy to reach it or hard is beside the point. Cap exist.
I believe that because there is no real dependency of stats vs the natural quality that this problem arises. Stats are important to reach the cap, when you reach the cap, putting points in that specific stat loses all meaning.
These are huge issues that the game possesses and as such I cannot see a permanent world being a thing yet.
