You're simply refining the question, not providing an answer. So, with your post in mind, when is the "well being" of a monitor not being met? Gary Quirk has bred many, many arguses, and has kept adults in cages as small as 4'x4'. Same thing with Patrick Nabors.
So, it's obvious the "well being" of a monitor certainly cannot be defined as reproduction based on your standards...but isn't reproduction in large part transpire once good conditions have been provided? Do you know of monitors who reproduce in poor conditions? My point is: if reproduction is not a signal of "well being" in a monitor (which happens in small cages)--what in the world is?!
"Well being" is subjective at best. I sure hope you're not implying that, if you cannot supply a 16' cage, you shouldn't own an argus. I mean, I know you love to start arguments with me, but come on...

To me, it's a good idea to always carry two sacks of something when you walk around. That way, if anybody asks, "Hey, can you give me a hand?" you can say, "Sorry, got these sacks." -JH
