These all sound like good suggestions to me.

I don't see anything "paranoid" about recording sessions. They're the client's sessions after all and unless someone is going to upload them on YouTube I fail to see the problem.

I recorded all my sessions, most of the time without informing the therapist who would have objected to it of course.Mhm wonder why

I find it odd how people use the law as some sort of objective criteria. Lots of things are perfectly legal and completely immoral and unethical.
Laws aren't made in a vacuum, they reflect the society we live in. After all, it's perfectly legal to marry 9-year-old girls to adult men in various parts of the world.

I think for people like the OP who were abused it's perfectly natural to find ways to protect yourself. And of course abused clients don't trust therapists. That's basic common sense.
