Tires do come off rims in blowouts, but you have cause and effect reversed.
A tire coming off a rim is a common cause of blowouts, but blowouts don't cause tires to come off rims.
In any case, even accepting the risk that the tire magically jams the wheel (which by your analysis is very small), how does that compare to the general risks of riding in traffiC?
Let's be realistic and consider that the risk of catastrophic failure is small, and the likely consequences of failure are minor, so, by riding this tire one is taking a small chance of an event that's not likely to have dire consequences. Now think about all the stuff that are far more likely to happen while riding every day.
