Most tires have very light casings which lowers weight but causes the tire to roll under heavy cornering when the pressures are around 20PSI. If I run a tube that roll is much less pronounced.
Tubed or tubeless... if you want to run low pressure you need a tire & wheel combo that suits your riding style and works together.
I wouldn't say MOST tires have very light casings. But if you are going tubeless primarily for the weight savings, and therefore decide to go with the lightest "tubeless ready" casing you can find, the bike will feel squirmy compared to a tube setup. Especially at low pressures and with narrower rims. I have made this mistake before.
Your last point is key. I run tubeless, but I have learned that I need to run a slightly heavier casing (Schwalbe SnakeSkin, Maxxis EXO) than I otherwise would.
That is fine with me because my reasons for running tubeless (in order of importance) are as follows.
1. Prevent small punctures (thorns and such) from ruining my ride.
2. Benefits of lower pressures without risk of snake bite ruining my ride.
3. Because it is rad. (all the cool kids are doing it...)
4. Rotational weight savings.
