I haven't read any of the replies yet, so I have no idea what your statements are. That said, the single one you made in reply to me doesn't hold up. "Not the way it was originally intended to be played" has no bearing on how it is played today. Want to look at D&D 4e and say that because Chainmail wasn't "intended to be played as heroic/high fantasy" that D&D 4e has player characters as mundane? That's pretty obviously not true, so original intent can be removed as a discussion factor for how the game is currently played.
It's interesting that you feel that is not "the way to play D&D". Mechanically PCs can do things a mundane person can't. Jumping down 40 feet and continuing to fight. Getting hit perfectly by a club wielded by a giant and still fighting. Fighting at full strength even when badly wounded. I don't know any players that penalize themselves above what the rules say in order to play as mundanes in D&D - they play to the heroic tropes.
This isn't opinion as you dismissed it, this is observation of both what the PCs can do as defined by the physics of the rules - above the mundane - and how people play them - at the level the rules allow them to.
