Yeah this could never be practically effective, not only because it would slow an online game down to live speed which the vast majority of online players would not accept, but at some point you have to either digitize or input the card values in order for the software to do anything with it. Not to even mention the logistics and costs of having one human being per online table. You think player liquidity is an issue now? LOL.
As I keep pointing out, no live dealer nor even a shuffle machine could ever shuffle physical cards in a more random fashion than a computer. Electrons and data bits don't stick together like live cards do, and can be shuffled billions of times in the time it takes a dealer to finish one riffle shuffle.
Besides, even a live dealer wouldn't quell the diehard rigtards, because the first "bad beat" they took, they'd insist the dealer was shady and impossible to verify since s/he's remote and inaccessible.
