There seem to be two stories - the prison planet and the planet of evolution - with ever more information coming out about both of them. I'm beginning to get the impression that they are both correct and that the evolution side is using the prison side for this.
Farsight reduces the excarnate entity to a single 'isbe' and does not differentiate between that of plankton and human, yet there is a persistent story of our 'higher self', connection to source as co-creators and our long-term mission to endure this blasted planet in order to raise its awareness and spill out creativity into the rest of the galaxy, in a nutshell.
People might get their memories wiped but some are more intelligent than others, some have more extra-sensory perception than others and some people do seem to simply remember stuff in a non-specific 'oh this is all very familiar' kind of fashion. This ties in with the idea that there isn't just one species wearing a human shell and the notion that some souls (bits of god) have been round the block more times than others. It's like the memories get wiped but the wisdom doesn't.
It all seems to be converging right now. The spiritual johnnies talk about 'the Shift' of consciousness of both humanity and the planet and ufophiles about disclosure. Both say we are on the tipping point so it's a battle on every front.
Consent - well, you said it. A mind maliciously interfered with cannot give informed consent. I'm sure an honest terrestrial court would take that into account, never mind an advanced civilisation. The idea that we must go down some sort of legal route with contracts and signatures by whoever on everyone else's supposed behalf doesn't ring true. Sounds more like a distraction to keep is in the mindset of the old control structure.
I bet you it's more about the energetic signature of humanity. Enough people waking up, one way or another, and saying "bugger this! I want to be my own boss." You can feel anger, shock, joy, etc. when you walk into a room so I'm sure an observant, concerned ET would notice a change in the planet's zeitgeist. Which brings us back to disclosure in every way possible and raising our consciousness at the same time.
