Who wants to play as a herd member for the sheepdogs to protect from the wolves?
You got that logic upside down. The people (herd) want protection (bodyguards, police) to increase their security, protect their lives and property. The bodyguards don't have a job unless the sheep employ them.
If it was "fun" then it would already be a common occurrence..... and Solo has always been just as much a part of the game as Private Groups and Open - as they were announced at the same time when the game design information was published at the beginning of the Kickstarter pitch.
Most MMOs do not add a solo-mode because MMO means Massively
Multiplayer Online. Not Solo Player. You can play by yourself in an MMO, but you need to be more careful and that makes it more fun. Carebare single-player environments creates lazy gameplay where people just switch to the other mode to escape risks. If they want security they will join a guild, corp or stay in high security areas.
This is why ED feels more stale than true MMOs because many people play in solo or private groups.
There are many threads about this, Frontier won't change it though.
