The OP asked about five seats, not necessarily together. For many performances on sale now, one can find five good seats in the orchestra that are reasonably close together and are not listening only. It's easy to buy pairs together. Discounted? No. But not obstructed view and very easy to get just by going to the website. Lucia, which I would consider an Italian opera, is one of them.

The reply made it sound as if tickets to La Scala are impossible to get. They are not. Five together might be tough, but not impossible for some operas, and everybody will see the stage.

I just went online to the La Scala site and had two orchestra seats in my cart. Total price 540 euros. I recently bought two orchestra seats to Carmen. Total price 540 euros. I could've had lots more in both cases. Easy.

I think the correct answer would have been that discounted tickets are very difficult to come by but face value tickets are not for many operas.
