I'm certainly not an expert on what the developers have or haven't said about the game - I'm new, as stated, and am just coming to it now, in mid-2020.Oh, and the Dangerous thing has been done to death, so you're coming across trollish now.
Sir David himself said that the Dangerous refers to the rank, not to some hypothetical dystopian element of lawlessness. If it were really as you imply, you'd never get into an Imperial/Federal Coriolis with any significant amount of bounties. They'd be scanning every ship that asked for docking, and blowing you away as soon as you got within range.
And yes the "keeping Elite dangerous" thing has been done to death, apologies for that as it is cliche.
But - there's an element of truth to it. I never think or worry about NPCs in a system. Evading an NPC interdiction is the height of triviality. Other players, however, are another thing altogether, and their presence forces me into an extremely enjoyable decision loop that influences everything I do as long as they are around. Do I immediately high wake? Can I get to the station without getting interdicted? Do I interdict them? All of these options are on the table, and that makes for engaging gameplay. It's gameplay challenge and interest, and what I enjoy about Open, regardless of whether any PVP actually results.
