I can make that statement because, unlike you, I don't generalize. You on the other hand keep pointing out shit in the UK and saying it would work over hear, despite completely different circumstances, culture, resources, and a host of other factors.
I am dependent on other people for many things, as it should be. Humanity is a social species. But that doesn't mean there is no value of self-sufficiency. There's a difference between making use of other people's advanced skills and taking care of myself. I don't go to the dentist to brush my teeth every night, even though he/she should probably do a better job than I could. Do you want your government nanny to Brush your teeth? I'm sure in the UK it could be arranged.
Getting back on topic, I don't hold the government responsible for my safety if I knowingly walk through, say, Camden New Jersey at night. Because I'm an adult, the decision to walk through it was mine, and I take responsibility for my actions. By your logic I should be able to sue the government for negligence if I get mugged.
If I'm going to rely on the government for personal protection, I expect an armed, trained bodyguard to follow me around 24/7. Until that happens, I'll keep my guns thank you.
