This doesn't create more demand for resources. It reduces supply. Less of a thing nobody wants doesn't matter.

In practice too, you're effectively nerfing the most common method of earning for new players (mining), and buffing one of the best for older players (by allowing people to have spawner setups last for multiple months).

 

You also have to factor in how quickly players with fly will zoom around and find all of the limited blocks like sea lanterns and whatnot. This only benefits the people who can day 1 reset scour the maps.

 

-1 spanwers gotta reset monthly otherwise I wouldn’t care

 

-1 resources would be very limited

 

-1 This would be an absurdly large buff to spawners and would kill the market for limited blocks like sea lanterns & Prismarine.

 

-1 I know some resources and good loot needs resets (like village, sea temples, shipwreck resources). Sea Temples in particular are usually void of sea lanterns within a few days at most (and sea lanterns are a building block, not an economy block), so that would bar that aspect.

 

-2 There's no real reason to change the reset interval other than artificial inflation of prices and demand by means of resource shortage. Besides, with the server being expected to grow in the near future (hopefully a lot), we'd probably end up rewinding this change anyways.

Not only is there no real reason to change it, but if you're basing your decision on current metrics, they'd be outdated in under 3 months either way.
Demand determines supply, not the other way around, nor should it be.

 

Denied based on the comments above.
PS: This would fuck with spawners, not something I'll ever consider.
