But the idea behind ham radio is that everything is open for everyone to learn, try and experiment, and not that you can have private conversations without paying your phone bills.

This is like having an open public square, and then someone decides to "privatize" an area, cordon it off, put temporary walls around and not-let anyone else look at (well.. listen) to what's happening there.

No, it's like reading an invisible book in a public square. You are may be reading like everyone else, but since no one can violate your privacy and see what you are reading they can't tell if you are reading something that is government approved.

But the whole idea of ham radio is, that anyone can ask you what you are reading, and that you're not wasthing that space with your privacy. It's about learning and technical experimentation and not about free private communication.

You want to take a bit of the spectrum away from everyone else and not let them neither listen nor join the conversation.

You can get a private frequency, pay a bit of money for that, and be private as much as you want.
