I agree that we are jumping to conclusions to say that flight from VMC into IMC was a factor in this tragedy.
However, it doesn't change the fact that untrained flight from VMC into IMC has been a contributing factor into past fatalities.
I agree with one (or both) of the Leads (Leadsled? Lead Balloon?) that we don't need more regulation. I personally am willing to accept these deaths as the consequence of being involved in aviation, the same way I accept the deaths (including those of close friends and family) in car accidents as not deterring me from driving. However, unfortunately, in my opinion, the travelling public fuelled by a hysterical media don't appear to share that view. A fatal car accident doesn't deter their wish to drive (or indeed improve their driving habits) but a fatal aircraft accident appears to mean that anyone who subsequently sets foot in a light aircraft is doomed.
And there's the rub....
