The trouble is there will always be a difference in quality. It’s a human business after all.
Different hospitals have different facilities as well. You’re better off having a type of procedure at one place than another for example. And even if you somehow made it so every hospital had the same high quality equipment you still wouldn’t have the same quality of specialists, surgeons, etc. This matters a lot.
There’s probably a baseline we could get to but the experience will never be a commodity overall.
