Please don't suggest that it is unacceptable to fly IFR without "licensed ATC service", this has been accepted aviation practice since time immoral.
Even when a service is theoretically available it frequently isn't available in practice due to weather (ironically) or the classic "controller workload" (such as making the tea)
What we do not need is more regulation or restrictions where none are justified.
However, anyone trying a home-brewed IF approach using a handheld GPS probably has a limited period left to enjoy their life.
