I think Sheet's saying that if it can be done once intentionally, it's clearly repeatable in enough frequency after practice that you would be able to beat the game. The site I did the most reading at is:

The thing is, I didn't spot any discussion of moving up in limits, they mostly seemed to be content staying at $5 minimum tables. Aren't there people who bet black chips on the pass line? How large of a bankroll would you need to withstand the variance at a $100 pass line bet, assuming you were beating the game? It seems like very few people worldwide could even accomplish +EV shooting, much less want to do it as a job, is I guess the reason we haven't heard about it.
Is it cheating to roll the dice intending for them to stay on axis, though? Isn't that very similar to using shenanigans to put cubes that are weighted to not land on two faces into the game?
