When you elect to take more three pointers you necessarily have to resort to shooting more difficult ones, which lowers the expected return on each one. In the real world it's not so simple.
Similar reason why star players often have lower FG% than one might think: they are the ones tasked with trying _something_ when the shot clock winds down and there's no clear play. Not all shots are chosen equally.

But then 2 pointers become easier. You can’t defend tightly both the perimeter and the paint at the same time. Sounds like a win-win. Again, nobody seemingly noticed.

Well yeah, the idea is not to go all 3-pointer, it's that the borderline decisions need to adjust a few notches in favor of attempting 3-pointers, until the returns are balanced out.
