Your math is not quite correct. There are several factors that you aren't considering. You aren't factoring the moment arm of the actual unit itself. You also need to consider some of the additional forces that will act on your hitch that this carrier imposes.
The tongue weight and the total weight are not the same. Otherwise you could have the bike on a contraption 10 ft long behind the car and you would say your setup is ok. There is a moment arm away from the point where the weight is being imposed.
Couple of other things you have to consider with these carriers - they impose rotational forces on the hitches as well as the forces they impose is different than a hitch/trailer would. A hitch trailer has forces that apply its forces straight down on the tongue, with some side to side forces (yawing). This particular carrier puts forces in a few different directions (including rotataional). Not saying your hitch can't handle it, but I wouldn't feel comfortable with anything less than a IV hitch.
I've used a carrier like this a few years back for a Vespa scooter. It was also a Class III. After 1000 miles (going to Maine/back) - it has ever so slightly bent the hitch down about 8-10 degrees. So it might work for nice short drives, but I would be careful. the vespa is lighter than the Duc and it bent the hitch. . ..
Tie downs shouldn't be a problem as most of these have rings about 12"-18" away from the rail that you can tie the bike down to. The vespa was easily a two person job for safety (though one could put it off). For the Duc - I would imagine you /really/ want two people.
And not sure why people would complain about 4K for a trailer (though you can easily get /many/ cheaper than that) for a bike that is 20-30K. . . One mistake on one of these carriers and its a lot more than you want to deal with.
Good luck. I wouldn't do it but each their own.
I agree with ALL your points. The only reason to even consider a rail, is storage of a trailer, or applicable neighborhood regulations that do not allow a trailer to be seen - my particular problem! I like the idea of going on trips with my Pani right behind me, but for all your reasons (which I am aware of BTW) I probably will never push the button and order
