What makes you think oil at ~$20 is likely? The cheap easy oil is mostly gone. Even the Saudi’s are spending large dollars on expensive heavy crude to keep up production rates.
Setting aside the fact that you're making up weird stuff that I'm supposedly thinking (and why do you you think you can read everyone's mind and TAKE OVER THE WORLD like Blue Tentacle?), we probably want to just work with what is. The last time oil went for less than $20/barrel (2014$) was in '98, and it hasn't been there since. Markets are what they are and we need to make peace w/ 'em. Oil's now trading under $60 like it's been for the decades before this last one, and evidently the oil there is now is easy enough at the prices we got.
