Quitting the game will bring you back to the exact same location while mode switching will allow to bypass the danger and reach guarded goal/resources with the hat of invisible man.
Are you worried about them missing out on exciting and challenging gameplay or the inability of large PVP orientated groups being able to lock other players out of lucrative trade routes?
The ability to control the level of human interaction by going closer or further from spawning areas is the brilliant idea, yet it doesn't stop the carebear's outcry. They're very demanding and despotic monsters. They want all or nothing.
Anyone who disagrees with you on this is a carebear? If we're in to such black and white territory; Does that make you a griefer. I'm sorry, but no, the above just means there would be no-go areas for players who aren't part of a big group and that doesn't sit right. What it does mean is that those who are part of a large pvp group can't rock up mob handed and close off a system as it'll just drive people to solo play - they'll need to fight on more even terms.
