"Why lock my door, people will open the door if they want to, or break the window."

I don't see what's wrong with having fewer things in your life which can silently kill you.

If you get in a new car, you are now completely at its mercy. There are few or no precautions you can take; you might as well lay on your back, and strap your arms down so your belly stays up.

What you're really doing is making it cheaper and easier to kill, misdirect, or trick you. This means that people who wanted to do these things before, but couldn't afford it, now can.
