Why a Proxy makes sense (as a security device for exploring the web)

The Proxy is the ultimate security device, and I am going to make my case by an analogy. Let's say I need to go to some dangerous place, for example, my Inlaw's or my younger daughter's room (translate this into any treacherous place).

The safest alternative is to not go.

The next best thing, is to send someone else, Right? This is exactly what a proxy is designed to do and there are things that are possible in the virtual world. A proxy
can:

• Perfectly impersonate you
• Transmit the whole experience to you, safely

For this to work, the proxy also does some other things -besides having to be a heckuva robust machine-, to know:

• It has to know where NOT to go
• It has to know what not to touch, eat (or open, execute) and how to get rid of some stuff

On the other side proxies are not perfect, they CANNOT do all you can do. They usually don't speak all protocols, they give you a watered-downed version of the experience in some cases and on top of that, they have to know all your stuff to properly impersonate you and they will know all the nasty places where you want to go...
