I have agreed with everything you said right up to the second clause of your next-to-last sentence.
Goodbye, and any other Scientologist, is NOT free to do to others whatever they can convince them to submit to.
Licensing is a practice that governments use to protect the public from ignorant, unskilled, or destructive people operating in fields that can be dangerous to society.
For instance, if a plumber does not know what he is doing, he can hook the sewer up to the water faucets of every apartment in an apartment building, and sicken or kill every one in it. So they license plumbers, and require that they have the relevant training, and that they do all their work per code. And when a licensed plumber makes too many mistakes, or harms too many people, they pull his license and do not let him practice on people any more.
Given what we have all seen from the dangers of auditing, I believe that it is quite necessary to license auditors, just as other therapists are licensed, in order to protect the public from ignorant and destructive practitioners of Scientology - which are everywhere nowadays.
The Church of Scientology's training and certification program has proven to be a complete joke, and they have proven themselves to be thoroughly untrusted to protect the public from harm.
It is time to delete Scientology's "rights" as a religion, move them over into being a therapy business - just like all other hypnotherapists - set standards for their practice, and license them.
Then, the next person to receive Scientology services who kills their mother like Jeremy Perkins, or any of the other tragedies that came about as a result of Scientology, those who caused the situation will have their licenses pulled, and face prosecution.
People will still be free to practice Scientology as much as they want.
But they will no longer be free to submit people to harm.
