I don't know what aircraft you flew on over 3 years ago. The current options from Etihad are Boeing 777 and Airbus A380. The route doesn't seem to be nonstop anymore, aboard any airline.

Along the shortest distance -- great circle route -- there aren't many options for an A380 to land and find support equipment mid-route (shown below). Refueling can occur with the passengers on board, there is a procedure to be followed, which includes alerting the fire service at the airport to be ready.

If we take only the cost of fuel into account, and a 777-200 as a baseline, actually stopping every ~6 hours is more economical. (This doesn't take into account landing fees, accrued cycles*, passenger convenience, etc.) Not just for your flight, but any long-haul flight; the fuel burned to carry the fuel for long distances becomes considerable after a certain range.

Another consideration is which freedoms of the air, say Etihad/UAE, has with say Russia. The second freedom specifically is:

The right to refuel or carry out maintenance in a foreign country without embarking or disembarking passengers or cargo.

While they are called freedoms, not all country-pairs mutually allow all the freedoms. The specifics are usually not public and are contained in the air service agreement between any 2 nations.

In all, it might have saved fuel even if we included a detour off the great circle. It certainly would have increased the maintenance cost. And it would have been an operational nightmare to arrange compared to a hotel and meal.

* Pressurizing and depressurizing, applying the takeoff thrust twice, applying the brakes twice, etc., all increase the maintenance cost.

Re: comment about London or Sweden already being destinations:

Already having flights to Sweden, UK, or Italy, doesn't mean the 2nd freedom is guaranteed. Note that "not many options" $\neq$ none. The middle half of the flight is either over tundra or the Arctic Ocean. An airport like London Heathrow won't welcome an on the spot request for a slot; busy airports in Europe are running near max capacity, so unless it's an emergency, on the spot slots really aren't realizable. Three daily slots to land at London Heathrow (as a destination) already cost Etihad £46.2 million back in 2013.

Short answer: Just fuel-wise, it might have (incl. a detour off the great circle) -- maintenance-cost-wise, no -- and operationally, it would have been a nightmare to arrange.
