There is a psychological trick that makes you think there is something worth doing if the wild is to be reset. Sure, there are resources left still atm, but that's not a great reason to say no.
And the price of items fluctuates normally regardless of a wild reset. After two weeks of the reset the prices will rise again to the meebles they were worth before.
It would also help the market for items such as shulker boxes and elytra, because they are so rare nearly no one has them in stock. And the people that do have them decide whatever price they want and others are forced to buy at that price. (If I tried selling a shulker box for 8k, it would probably sell within an hour even though I bought it a while back for 3500)
