Flatfiler, the dog isn't dead.
I'm having fun here, back to the subject.

I disagree, Sugar maples are beautiful open grown trees, but require lower braches to protect their roots and trunk in this environment, as you know they are understory trees. They have thin, shallow roots which don't stand the hot sun beating down on them, guess what, low branches make shade.
JPS also mentioned that whorled branches may enlarge and girdle a trees trunk. I am not saying all structural problems must be ignored below 15'. I would recomend repairing problems early.
Low branches are not a structural problem, they benefit the tree in many ways.
JPS also asked:
"Where am I being silly?"
Your logic that forest trees shed most of their lower limbs, therefore all lower limbs should be cut off homeowner's trees... that's silly.
Using that logic, the girl in that last jpg has really big boobs and everyone likes her, I should get big boobs and everyone would like me.
Here's a good one:
"Whay should the tree put resourses into a part of the system that will probibly be hacked off by someone else a decade or so in the future? "
Correct me if I'm wrong here, but doesn't a limb put resources into the tree?
Try to think of a limb like a seperate tree, if you will. When you are deciding how to trim a branch, do you automatically remove everything for 6 to 8 feet out that branch?
Let's use your arguements:
If you look at branches in the forest they often don't have lateral branches for the first 6-8 feet.
Those branches might whorl and girdle/kill the branch.
The new homeowner might not like them and the tree will have wasted resources growing them, only to have them removed.
Some species grow with branches like that.
It could be codominant.
Conclusion:
All the books are wrong, liontailing is good!
When a skilled arborist trims a tree it becomes a thing of beauty. For me the beauty lies, in part, in knowing that the tree was trimmed for long term health. Trees which are raised up, like a forest grown tree, and then grown in the open, are put in a very stressfull situation with poor long term prognoses.
There are valid reasons for removing limbs, and we all know these reasons, being low is not a valid reason to remove a limb.
