I actually like the mechanic that ressources are only regenerated after the chunk is fully up again. Like @Tagris said this encourages exploration and flexible behavior of the players to find the best spots for them. As long as we have (will have) enough planets to spread the whole community on this will lead to a more varriating experience then “hop through a portal, drop down and dig into the ground so that nothing kills you on your way” ^^. On this way people will have to face the dangers on the surface and later underground (hunters!!! ^^) before they get to a really good spot.
And as a last point it will lead to more portals, even if locked behind guild doors, which lead to locations worthy of mining/gathering and “Wandering” outposts because after a region got famous it slowly becomes the time to look for the next fortune 
Now we just need to have the xp for chisteling outside of beacons removed so that those powergamer madmen stop to ruin our wonderful planets and sabotage the surface regeneration ^^
