There is no social entity with a good that undergoes some sacrifice for its own good. There are only individual people, different individual people, … - Robert Nozick

Once a person exists, not everything compatible with his overall existence being a net plus can be done, even by those who created him. An existing person has claims, even against those whose purpose in creating him was to violate those claims.

You can't satisfy everybody; especially if there are those who will be dissatisfied unless not everybody is satisfied.

There will not be one kind of community existing and one kind of life led in utopia. Utopia will consist of utopias, of many different and divergent communities in which people lead different kinds of lives under different institutions. Some kinds of communities will be more attractive to most than others; communities will wax and wane. People will leave some for others or spend their whole lives in one. Utopia is a framework for utopias, a place where people are at liberty to join together voluntarily to pursue and attempt to realize their own vision of the good life in the ideal community but where no one can impose his own utopian vision upon others.
