For most of the world, war between two countries in the middle east doesn't really have any direct impact, right? Liek, if I didn't know about it, nothing would change for me.
I feel like it can matter a lot to be able to make a reasonably reliable prediction about whether it's likely to go up or down tomorrow and by about how much, and thus whether and when to act on the potential need to ensure some sort of access to supply.
For me, that largely entails just not doing anything. I do own a car but rarely use it since my neighborhood is very walkable, and the tank is usually close to full. Even my lawn tools are electric. But if I relied on gasoline for a commute (for instance) then being able to make good guesses about getting hold of it is advantageous, in a way that is fungible and easily shared.
You say that as though they were two semiotically distinguishable activities. Futures trading is wholesale and what we talked about is retail, but they are the same general line of business and if you think no one would ever do it to try to avoid waiting all day for an empty pump, then check out how the 70s oil shock and supply crisis - the last time anyone ever dared "sanction" the U. S. and A. - played out here domestically.
If it is supply you are actually concerned about you buy a couple jerry cans that you keep full. Watching geopolitics to try to time anything still makes no sense.
