What ? You and your friends make a private club, round up people who you deem a danger to themselves or society and lock them up for life at your own expense?
Are you serious?
Is this really your proposal Fred?
I'm not sure what you mean by private "club". And you make "round up" sound like a cattle drive.
I certainly don't do things for free either, unless I'm so inclined.
So in your dream society, mentally ill people will be incarcerated for life and charged for it. You think that someone who is so ill that they are a danger to themselves or society is going to be able to pay for 24/7 medical care.
That's delusional. Really even for a person who doesn't like to deal with the real world such as yourself, that is daft.
