Given the choice I would not prefer to have my gear transported by someone else, be it a SAG wagon or my butler riding beside me, in order to appreciate an unladen ride... I love hauling my gear myself.
I wouldn't want my gear transported for me either. A motor vehicle along would pretty much ruin the experience for me. I too love hauling my gear myself, I just prefer that there isn't any more of it than necessary to camp and cook in reasonable comfort. I also find that taking a sportier bike is a plus and I don't consider that a good idea with heavier loads.
That said I do like to minimize what I carry, while maintaining the ability to camp, cook, and generally be pretty self sufficient. Sagged tours or credit card tours are both less appealing to me. A simple lifestyle on tour with minimal possessions along is very pleasant to me.
