Future trades are certainly not zero sum. There’s always a spread.

There is more volume in calls then in put option - these are really executed and create a lot of demand at a certain time. As you say you have to clear it - buy actually buying.

What was ment as a price ensurance drives demand. Not the real demand.

That's funny!

There’s always a spread.

But the trades are executed at a price, not at a spread.
