How would you trade if you knew the future but not the path?

I saw a tweet:

Let’s set aside the obvious “just short bonds” response to a crystal ball that tells you mortgage rates are going to roof. While I’m not sure how volatile the 10-year note/MBS basis is, just shorting bonds would seem like the most direct and reliable trade.

The rest of the crystal ball portfolio underwhelms expectations. Ahh, a recurring parable in the “trading is hard” bible. Like if you knew what a stock’s earnings were going to be would you be able to make money? How do you know what the “whisper” number is or if the market is focused on guidance more than income for this quarter?

It also reminded me of 2 adjacent reads that cut to the heart of “how would you trade if you knew the future but not the path?”
