I believe that is a utopia, because of human nature. There will always be something you will want to not tell beyond your family or friends, things youe government might think inappropriate by the societal standards at a given century, and so on.

There are things that only should matter to me: my wealth, health are among some.

Society's views on matters change over time. I dont belueve there will ever be a time where "anything" is ok by everyone.
