While there are larger and smaller infinite sets the two sets you give are the same size. They are both countably infinite. A way to see this is that for every element in the set of even positive integers there is a corresponding positive integer and vice versa. All math is abstraction, and you need to make sure it applies to the current case. In this case it doesn't: infinite resources don't exist.
