Simply and true; NO.
UNDERinflating is the cause of death for many tires. People check their oil but forget about the tires when loading their family and weeks worth of luggage in their cars to visit the sunny South. The overloaded and underpressured tires overheat and delaminate and burst.
I am aware of what I do. I regularly kill the stereo, roll down the windows and listen; tires, brakes, exhaust, anything out of the ordinary? I wanna know, so I check.
Not just on my car, but my wives, parents, in-laws car; anyones. They are unaware. I see one of their tire sides bulge out, check it and yup, 7 PSI below door sticker so WAY low. They did not notice.
When a tire blows at anything below 200 PSI there must be something wrong with it. The carcass is cut or whatever. But what stresses the carcass is not the pressure but the repeated flexing. the higher the pressure, the less the carcass deforms at each rotation, and if the tire already was damaged, the slower that damage will increase.
Tire companies sell tires. They know what makes a tire last long and what not. Low pressure sells more tires. It also kills people. What a shame then to blame the experienced and investigating people who raise their tire pressure, even though they find only benefits from doing so?

I absolutely agree with the reasons you've given that an under-inflated tire is dangerous. For that reason, and to increase FE, I increased pressure by 6 PSI over the door sticker.
Hey, it's a free country. If you want to inflate your tires to 200, or modify your car to run with bicycle rims & tires - fill your boots. I'm sure someone on the Internet says it's perfectly safe to do so.
