if we are properly rolled my guess is allowing for increase in variance also increases our EV
This concept probably helped me the most when I was starting out. I was definitely not rolled properly so oftentimes I was avoiding variance and missing value on premium hands.
However I don't think that's necessarily a cardinal sin of poker if you're a rec player who puts in less than 500 hrs a year. If high variance puts you on tilt and makes you play worse overall, is avoiding it really that big of an EV loss? That's gonna be the mentality of a lot of players you have at the table, which is, again, exploitable in some cases.
But that's level 2 poker and I'm not quite there yet.
I won't comment on the rest of your post, because it makes a lot of assumptions that are casino/table dependent.
