Yeah the Warriors, especially now with Durant, really seem like they are about the closest thing to a perfect team built as close to perfectly for this era that you can get. Playing at an advanced level within a system of basketball that is about as perfect a match as you can have.
You're right, you have to kind of step back and remember that when you are analyzing teams losing to them in the playoffs.
I'm basically just retreading ground, but the only world where I see a healthy Warriors team not make the finals for the next few years is one where Lebron coordinates going to Houston, they resign Capella, and ideally buy cap space on someone's roster to take Anderson and fill out the bench with 3 and D ring chasers. Essentially creating another all-time great roster. If you are the Wolves, Pelicans, Thunder, or Blazers, you would definitely be wise not to make major organizational moves because you can't beat GS. Lebron to Houston and Lebron and friends to the Lakers is probably your only real chance...Basically, if your already close to contending team can't land Lebron, I wouldn't sweat losing to a healthy Warriors.
