I think it is impossible to completely replace a live casino. Because there people pay for the atmosphere, and for the game, and for communication. Many of this will never be online.
I think your statement will be misunderstood.
People or gamblers go to casino to gamble, they are not really there for the interior design, the people drinking, people that are cheering because their card showed up. They are the features they wanted but not the reason they went there. Though, we never know right? VR might take gambling to the next level.
