Anti-dualistic social ontologies, those highlighting the intrinsic interdependency of agency and structure as two sides of the same coin, are sometimes criticized for failing to provide a satisfactory account of autonomous -- capable and free -- agency, or even denying the reality of such agency. This paper contests these claims, arguing that anti-dualistic ontologies only conflict with autonomous agency when the latter is understood in a highly voluntaristic sense, whose ideational roots go to what philosophers of free will call "incompatibilist" intuitions of freedom. Those intuitions suggest that actions (intentions, decisions) ultimately determined by extrinsic causes lack the kind of freedom presupposed by moral responsibility, so when agentive autonomy is presumed to involve such freedom, it does indeed cohere poorly with the anti-dualistic picture of intrinsically structured agency. Herein, however, an alternative, "compatibilist" notion of autonomy is advanced, such that does not conflict with extrinsic determination and is therefore congruent with anti-dualistic social ontologies.
