I am not discounting your observations but I still think you might be underestimating the damage that could be done by a well-bankrolled team that was allowed to spread freely. How does the casino protect themselves from the best counters but not discriminate against counters in general. The positive effects you mention would not begin to compensate the casino for the money they would lose.
"...nothing drives suspicious players from the table like consecutive dealer blackjacks.
I personally believe you most likely remember this very well because when it happened, you had a large bet on the felt."
I am no mathematician Stealth Bomber but I believe that there are more naturals in high counts both for the player and the dealer. More big cards makes more blackjacks, right? Assuming, of course, that the high count includes aces and ten value cards. I was not referring to memory (selective or otherwise) in making that point. Nothing upsets ploppies more than a "lucky dealer" and frequent blackjacks are seen as a pretty good indication of luck.
I think you might be better off accepting the reality that the casinos don't want you there and figure out ways you can deceive them into letting you play. If it were easy, socially acceptable and comfortable, then many more would do it successfully and countable games would no longer exist.
