Once you enter an area that requires a ticket or that is private property, you are no longer in a public venue for free unhampered expression; you are in an area for paying customers.
And when the goverment has finished selling just about all of the public land, train stations, bus stations you'll get to enjoy your lack of freedom to speak in those oh so not public places, you know, the ones where the public walk around and you have to use to access "public transport" yet it is private property...
It may be "common sense" to you, but I don't see how you don't realize what you just said is impossible - at least in the sense of providing the "best" healthcare for everyone. There are documented horrible failures of British and Canadian healthcare for instance - you are at the mercy of a bureaucracy in order to get treatment. Often the wait times are measured in months. There is a reason so many wealthy foreigners come to America for major procedures.
Just as with your ideas about taxing the rich, there are unintended consequences. Many doctors are quitting the profession because of 0bamacare.
Yeah cause I am sure some lapses in health care are much better than having no chance of having it all, give me a break.
