Okay, you're clearly not a libertarian and it is inevitable that you are going to disagree regardless.
I agree with you though, and you are referring to what is Libertarianism in its most extreme form. Obviously there would be some taxation, though only to cover essential needs like, as you say, street lighting, and other key needs like securing a healthy democratic society, and the need to fund the police and fire services et al.
I'm not advocating complete individualism and isolation from society, I am merely applying libertarian values to common sense.
