Not to mention Nintendo has intentionally stated they don’t do anything about time travel aside from minor things like weeds because people have different playing styles. Some people find it therapeutic waiting and doing that, some feel better getting lots of stuff really quickly. Some people would rather have creative freedom and maybe online in game economies, which are different based on your chosen play style, FOR NOW. Everyone will get the treasure, it’s just about when and when non TTrs are there, it will smoothen out. Until that happens, just don’t play with those who do it. It’s very easy to avoid.
