I'm not making an "I hate PG/Solo" rant (I'll save them for a rainy day), but ED clearly caters to the solo player too much to be any kind of true natural galaxy
A galaxy in which EVEN a small proportion (1-2%) of peaceful Journeys Trade/Passeneger/Data Delivery etc etc resulted in destruction of the ship that was carrying out that journey, would be a Galaxy in which there was ZERO trade between systems...
(For example Ship Tonnage Losses during the Battle of the Atlantic ran at over 2% for a few months at its height...ENOUGH to have crippled the UK if it had continued for much longer and enough to ensure ALL merchant ships traveled in heavily escorted Convoys)
It'd also be a Galaxy which didn't have ENOUGH active trade to support any kind of Piracy etc...
So yes, MOST journeys being carried out without any risk or interruption DOES seem like a "True Natural Galaxy" to me
