Is it though? Warriors drafted all but KD so it's not like 3 other stars signing with one. The Warriors drafted well (Green, Thompson, Curry), curated their talent and have players that don't require to be the highest paid (well, outside of Curry). They are the perfect storm of circumstance, as they completely benefited from the new CBA. This won't last, though. It will end soon, just as the Miami "super team" ended sooner than expected.
What you described of the 3 players coming together was what Lebron/Wade/Bosh did back in Miami, not what is happening with the Warriors.
Yes that is a good point. So the equivalent of Durant would have been Shaq joining the bulls after the 1997 season. Still bad.... I'm hoping it falls apart in GS soon because it would have made for good basketball/ competition if Durant had stayed with OKC (or gone to another team that did not win 72 games the prior season).
