If someone didn't have family to fall back in, an empty bank account would literally ruin the life of the average American.
Here, the banks offer very limited credits, expecially to foreigners like me. Public health care and education is not great, to put it nicely. My family depends on my income but a bankruptcy would mean that I would lose my license to practise my profession, and so too my income would take a dip.
So, losing cash could mean that I would loose my profession, my home, car etc. There would be no more nice kindergartens, no nanny, no cleaning lady or private doctors for a long while. We would eat less, drink less, travel less etc. But that doesn't mean that my life would be ruined.
You're talking about eating less. You're talking about still being able to travel. I'm talking about a country where roughly one-sixth of its population would literally starve if this happened to them.
The first 4 you mention do not magically come for free in the U.S. You might retain the 5th, if you already had a job, and though you were nice enough to mention 'no physical injury' you somehow neglected 'no psychological injury'... though I can see why, since it would be untrue.
All of these things can hinge on having money.
2) If you're not in poverty, and your employer direct-deposits, all of the above, only you can change your direct deposit destination faster.
