What I'm asking is, why is looking at it another particular way not valid? The perspective addressed in my question seems like a perfectly valid way of looking at things to me.
That's already answered, too.
So what your saying is that if players want to prioritise what you call "smart play" (a certain sort of Gygaxian/Pulsepherian gamism) over narratively-oriented play of the sort that the 4e-types on this thread are articulating - to the extent that they will push the game into absurdity to make their prioritis clear - then 4e is not the best game system.
No, what I am saying is that the hit point paradigm changed.
In further discussion of what the various hit point paradigms are, it did indeed come up that 4e isn't well suited for some types of play. BUT....I am saying that all games have "smart play" element built into them, whether intended or not. A well designed game harmonizes the "smart play" elements with the "intended play" elements, so that when you are doing the smart thing you are also doing the intended thing, and vice versa.
I am also saying that continued day to day activity while never taking any damage that prevents (or strongly counterindicates) continued day to day actiity, was intentionally written into the 4e system's "smart play" because the good folks at WotC thought, although the result might quickly become absurd, it was "more fun".
IOW, I am suggesting that, if good design harmonizes smart and intended play, and if 4e is good design, then the absurd features are intentional. Not intentional because they are absurd, but intentional because the designers thought them more fun
despite being absurd (or simply didn't stop to consider the absurd rammifications of the rules they were writing).
There is nothing "invalid" in playing that way, if you enjoy it. There is nothing "invalid" in not playing that way while using that ruleset.
But, for me at least, there is as much work involved -- every combat -- in making the 4e rules "make sense" within the context of the game world as some of you have expended trying to make the 1e hp rules not make sense.
I don't mind having to work to make things not make sense. I simply don't do that work. I do mind having to work, continually, every combat, for the rules to make sense within the game world. That is, simply put, not fun.
