There's a reason deflation hasn't happened since the Great Depression and that inflation was the escape valve (devaluing against gold and then mass austerity of personal consumption to rebuild savings and investment in the war effort).
Once we found Keynesian religion, and realized we could just print our way out of any mess (or default against the obligations of a hard currency), we did.
I used to think along the same lines as you - that debt was deflationary. And it is - for anyone who can't print their own currency. But we're the latter and currently have forced buyers of the USD regardless of how much we print (at least for now), so deflation aint going to happen.
Not to mention that other infrastructure in the area has been damaged/destroyed by Iran and nothing says new infrastructure wouldn't be under similar threats.
I don't know what the right price for oil is - but if we could hit $150/barrel in 2008, I don't see why $150/barrel today is out of the question. It would still be a significantly lower inflation adjusted top from 2008, comparable to the Russia/Ukraine episode, and reflects the ongoing supply shock, the increased insurance premium, AND that nations will need to rebuilt some level of inventories even if traditional drivers of demand fall off.
If oil wasn't going to head higher, I don't know why we're doing all of these reserve releases and jawboning trying to prevent it. I think it's clear that the price has been artificially suppressed and the only questions are by how much, and for how long, and how high will it go when that suppression stops.
