We know of no-one who advocates 'anarchy' in any of these senses. Anarchists certainly do not.
Anarchists adovcate anarchy in the sense of nobody being boss over anybody else.
Anarchism stems from the conviction that the purpose of society is to increase individual opportunities. For a totally isolated individual, the choice would be ,either to do what is necessary to stay alive, or to die. In a healthy sociey,each individual makes use of the others, and freedom of choice is increased all round. All voluntary co-operation is healthy, in the sense of fulfilling the purpose of society. Organisation is healthy,so long as people are doing what they want, and not being forced by the organisation to do something they do not wish to do.
