So, I reread your article once more (and this time in its entirety). Though the later back and forth only extended the initial, pretty well articulated, premise, I realized that I missed that Buddha quite early in the text, indeed, urged marquise to "taste Nirvana" and make up his mind. My bad.

On the other hand, a better title would be Marquis de Sade versus Siddhartha, because this is the kind of dialogue you can witness every time an ascetic and a practitioner of tantra, both of whom are still "searching", meet and argue which path is more valid (btw. Hesse’s Siddhartha elaborates on this dichotomy, too).

There is a funny scene (ca. 6:20–7:45) in a movie I saw, that illustrates the point you are making very well, and also captures the solution (though the rest of that flick is pretty atrocious :D).
