Yes and indulging this appetite is much like any other, a good comparison being the other fundamental one: hunger. I think that also frames it in a way that makes it more concrete as to what the negative aspects are as well as showing that total abstinence is not necessarily an unalloyed virtue. If you don't eat at all you will starve but you can easily eat too much or eat the wrong things and it becomes gluttony at the extremes. Coming up with systems that allow you to cheat the negative aspects also turns pathological in the long run. Deadly sins exist even without the religious framing but the spiritual, social and psychological aspects are very real regardless of what anyone professes to believe.

You've made a hypothesis, provided no basis for it, blew past that and built some more conclusions on top of it. Along the way you introduced a few more unsubstantiated thoughts.

The post in it's entirety reads as a religious rant, but it might have had something to offer to the reader if you had bothered to provide some sort of philosophical foundation for why you feel that the middle way is the superior way. And that all excess is inherently not only nearly identical in terms of effect, but by definition harmful.
