I don't know, looking at this chart is seems extremely easy to meet those amino acids with plant foods.

Just looking at lysine:
> There’s no official RDA for lysine, but according to research, you typically want to aim for about 12 mg per kg of bodyweight.
> For example, a 170 lb person needs 924 mg per day, or more.
So a cup of soybeans providers 1.33 grams, oats, lentils and any bean at least a gram per serving.
Oatmeal for breakfast, nuts for a snack and a mix of vegetables with some beans or tofu for dinner and you exceed the RDA for every one of those amino acids you've listed. All healthy things you should be incorporating into your diet anyway (fiber rich). So while a single food may not meet the RDA alone, it seems very easy to meet with a combination of common foods in a plant based diet.
Not to mention nutrients that are supplemented in vegan diets often are also supplemented in omni diets (B12 in meat and Vitamin D in milk, for example, are only because of supplementation and fortification).
> It certainly doesn't taste as good, especially if you don't want to take tons of time cooking.
> It still takes "gourmet" vegetarian food to compare to regular meat.
I had plenty of terrible meat meals and many amazing vegan dishes. I would say the standard American diet lacks a lot of knowledge about tasty ways to cook plants, but they do exist and they aren't hard. Ethiopian and Indian cooking, for example, have a strong tradition of plant based dishes that are easy to make. Many other cuisines can easily be adapted.
