I didn't read your whole post because I'm tired (it's late here) but you are generally correct from what I saw.

"I have read many posts on 2+2 to the effect of “you can’t beat the nano / micro limits because people don’t play like they should "


I don't see that many 2+2'ers who think this way.
Most of the time, if anyone even HINTS at that attitude they get torn apart.
If they are saying, "Ummmm...YEAH RIGHT. The reason you can't beat them is because they don't play right" then perhaps there is also an issue here of you not quite picking up on the sarcasm....because almost ALL long-time 2+2'ers pretty much understand that you WANT players who do not play correctly.

This usually means they are too loose and call down or raise with improper odds.

Ed Miller explains a lot of this in his book Small Stakes Holdem which you (and everyone else) should get.



Your blackjack analogy is very flawed though and I'm going to pick a bit of a nit about it.

There can be quite a bit of difference...but the casino still doesn't care because even if the player is playing perfect basic-strategy the casino still has an edge.

usually the casino's edge over a player playing perfect-strategy will be 0.5% - 1% (depending on the rules of the game).
Most players do not play perfect strategy.
(those of you reading this....if you THINK you play perfect-strategy, you are probably wrong. It is different than what 99% of the people out there think it is).
Those who play the 'generally accepted' strategy are playing a decent game still and are not making too many serious errors. Their disadvantage might be in the 1-1.2% range I would guess.
Then there are those who play just a generally bad game. Not hitting their 14 v. 9. Not doubling-down on their 11 vs. an 8 because they have a 'bad feeling' about it.
Their disadvantage has to be pushing 2.5% or higher I would think.
And then there are the crazy drunks who might double-down on a hard-6 or hard-12, or stand on a soft 6 (ace and a five), etc etc. They could be pushing 4-5% disadvantage.

Then there are the expert card-counters who might be operating at a 0.5% advantage.

This is really not all that different from poker where some players suck a ton and are at a 5% disadvnatage or so but still get some wins just due to variance and running lucky.
