There are a lot of conventions advocated by professional writers and editors that have the reasoning, "Because there is a better way to do it."
It's a lot easier to throw in an exclamation mark than to choose better words. For my writing, I'm fine with that at the moment. I'd rather concentrate on things that I consider more important than things like eliminating exclamation marks.
If you don't feel like taking the time and effort to write better, that's your choice (as I've chosen to do). Railing against the convention in the manner you did above, however ...
'Better' is subjective, but eschewing exclamation marks for the sake of eschewing them seems counterintuitive and 'artificial' as Russ put it.
