If one designs a diet based solely on fruits, nuts and veggies (no soy, dairy, etc) that meets ALL of the daily requirements for vitamins and minerals with the notable exception of Vitamin D which can be supplemented very easily and contains sufficient protein what is so wrong with that?
The diet would be very low is saturated fat and have no cholesterol so from a scientific point of view give me your objections.
Also - can you provide any studies which show that dietary saturated fat is necessary?

Still incomplete: retinol, K2, B12, taurine, carnitine, etc...
Also probably hard to get enough calories, many vegans have that issues (which is why generally folks lose weight until they're sticks, unless they're gorging on processed crap.)

Nothing I can say is going to be persuasive to you if you have made up your mind. But I'd say try a vegetarian diet out for a month or two, then try one that has animal products from happy animals eating a proper diet, and feel the difference in your own body.
I've spent most of my adult life researching my booty off about this stuff, and personal experience is what sold me on it more than any study or paper. I can't condense everything I've studied into a simple answer here either, so I trust you can do your own research and own due diligence on this one. I'd point you towards comparing large intestine length in primates, traditional dietary choices, and if you want a short cut, pop on over to Denise Minger's Raw Food SOS site. There are simply some nutrients that to be bioavailable to a human are best processed through an herbivore first. There are also often problems trying to take supplements to make up for what isn't found in the diet, and you get issues like the recent study and the TMAO debacle. Supplements were used in the studies, and the pre broken down supplements got digested higher up in the digestive tract than they would have if they were whole foods, leading to the increase in cardiac events. It isn't just what you eat, but how and where it gets incorporated into your system.
After spending the first 20ish years of my life as a vegetarian (who worked hard to get a balanced diet and took supplements to make up for what I was missing), I finally had to give it up when my hormonal health deteriorated to a breaking point and I wanted to start a family. My quality of life and health in general, the most noticeable change being in my mental health is much improved if I eat at least some animal based food every day.

You can almost live a healthy life on this diet. But you admit that it's suboptimal and relies on supplements. You could improve it naturally by adding seafood. If you're afraid of saturated fat and cholesterol that's the best way to go.

The main knock on Vegan diets I think is brain health:
Also the zinc to copper ratio is two low unless one supplements with zinc. Unfortunately bio available zinc is more difficult to acquire from plant foods. I would like nothing more than for this to be untrue as a former Vegan/Vegetarian. Zinc is just too important for the brain to give any credit to a Vegan diet.
Having said that thhq is right you can survive and live on a Vegan diet.
