Although I do see your point now about why NASA devised its policy the way it did, I just don't agree with your interpretation of it. Like I said, you do have a valid point, I just think I would have done exactly what NASA did, but not for the reasons you believe.

As for Titan's life, this place is really strange, its cold as hell and rains ethane and snows paraffin there, and water is a mineral. Life is theoretically possible but it would be extremely bizarre, so weird we might not even be able to recognize it as such even if we had a fully equipped human lab there. I doubt a microscope photograph of one of their bugs would even be recognizable as being alive.

The only thing we have on earth even remotely like it is the bacteria that grow inside oil refineries feeding on refined petroleum products. Carbon and hydrogen are present as long-chain hydrocarbons, but oxygen and nitrogen are not available in water solution. These critters and this environment is like nothing we've ever seen before.

I'm sorry if I came across too strong, you are making reasonable points, I just don't fully accept them.
