DFC,
"Furthermore, there is no requirement to call anyone while in Class G.........and if that is the choice we make then we miss that oportunity for an alerting service and the only one going to alert anyone is the person awaiting our arrival at destination."
Are you saying that you would rather file a paper flight plan before you go and rely solely on that, rather than make en route radio calls? I must have missed your point again because I can't believe anyone would. Far better to be in real time r/t contact with a ground unit if you have an emergency, rather than rely on a filed piece of paper when you aren't. It doesn't have to be London, just the nearest airfield.
Or are you just angry because in practice ATC doesn't work like you think it ought to?
