What you're saying is only partly true; it's true that physical dependence on marijuana has yet to be proven, but it has not been disproven either. I've been through withdrawal and while I'm sure it isn't anywhere near as bad as it would be for the harder drugs there is absolutely a physical aspect to it (i.e. vomiting, cold sweats, etc.).

I genuinely believe that there are some of us out there who have some physiological reason that marijuana affects us differently than others, and that as marijuana slowly becomes less taboo and people start doing research more the truth of the matter will come to light.

As /u/crazymush said, I think saying what you said trivializes what people who are trying to quit marijuana are going through and that those who read it may find it discouraging. At the end of the day nobody really knows what marijuana does to us physiologically and just because you had one experience does not mean there are not others who have had drastically different experiences.
