Possibilities?
1) Anarchists desire themselves and rebel against that which might take their selves away from them. That they recognize representatives or authorities can never meet their demands and thus, desire that which will give them the power to endlessly seek the objects of their desire.
The Commune seems to be a major object of desire because in the Commune, anarchists see a possibility for a mode of production and exchange that can facilitate this permissive desiring. In the Commune there is love, community, power, equality, difference, and the satisfaction of needs. Capitalism, the State, and Bureaucracy can't meet the demands of anarchists for the free commune. These forces are that which fill the role of the psychoanalytic "mother" - they can't meet the demands of the anarchist, the anarchist fixates on this lack and it becomes the desire. The Commune is also the psychoanalytic mother, but the present mother that can give the anarchist power over their life: the fantasy - the symptom ...revealing the lack inherent in anarchist desire. The insurrection as negative transference onto such an order, the absent mother: another fantasy and symptom, perhaps of separation anxiety. The conformist, the petit-bourgeois as the psychoanalytic father that naively reproduces the status quo - that which turns the present mother into the absent mother. The status quo has the phallus - the social revolution will give the anarchist the phallus. The anarchist desires society's desire for the anarchist's desire.

2) The Anarchist as Architect - as World-Maker. Since the Subject is also a World, the duel-desire of the anarchist is to return the lost power of agency in the realization of their self-world. Since subjectivity is intersubjective, the self/world-making is a collective self/world-making. The anarchist isn't solipsist ...doesn't desire god-like individual power and loneliness. To struggle, to suffer together until collective self/world-making can be created. Collective Self-Actualization.
3) The role of desire in anarchist philosophy is to demonstrate the extents to which we lack power under the rule of others.
4) The role of desire in anarchist philosophy as aspect of life that can't be enjoyed with the welfare state.
5) Make Total Bullshit!
