Many people share your opinion that they have (and will continue to have) no autonomy.

This is not a decided issue. Any policy that comes from the premise that this is a known factor is going to be inherently flawed.

You can never spend sufficient time considering the limitations you wish to impose. Almost all exploits found come from failing to consider something that allows a degree of freedom that you would have limited if you had have thought of it.
