You presume much about what services I use. There is much to be said about the power private corps have over us, the complications of being unable or unwilling to use their services making you a de facto outsider.
I don't see how these wrongs make another right.
Some of the actions alleged are actual crimes. It is a bad idea to have them handle para-legally. Sure being excluded from visiting bars is a light punishment (for someone actually guilty, completely unfair for an innocent person) but nothing guarantees it will stay there and won't also be used leaked to prospective employers and other people. In fact the first time you get denied you could very well not be alone and have to convince people you are not a rapist or something.
It's exactly the sort of information you not want bartenders and bouncers conjuring and trading in.
I think some fundamentalist Christians believe the earth is 4000 years old only.
Garbage in garbage out.
