<p>The rise of virtual worlds, collectively known as the Metaverse, compels a re-examination of longstanding debates concerning personal freedom, moral responsibility, and legal accountability. These immersive digital environments differ from prior communication technologies not merely in degree but in the phenomenological quality they produce: a pervasive sense of presence that blurs the boundary between the virtual and the physical. This article examines the ethical and legal challenges that arise when individuals choose to spend a substantial portion of their lives within such digital spaces. We introduce the concept of “Meta-Autonomy” as a theoretical framework for understanding personal agency in algorithmically mediated environments. We argue that existing accounts of autonomy — Kantian, procedural, and enactivist — each capture important dimensions of this challenge but face specific difficulties when confronted simultaneously with four structural properties of Metaverse environments: algorithmic mediation of choice architecture, radical fluidity of identity, networked and distributed causal agency, and the moral embeddedness of virtual experience. Meta-Autonomy is proposed as a framework that holds these four dimensions together and derives from their interaction both a set of diagnostic criteria for identifying autonomy deficits and a set of normative implications for regulation. We develop the thought experiment of “Plato’s Digital Cave” to illustrate the first-order/second-order autonomy distinction, and apply Meta-Autonomy’s four components systematically to specific legal questions — mens rea, legal personhood, distributed liability, virtual harm, and the regulation of Metaverse platforms under the GDPR, EU AI Act, and Digital Services Act. The article concludes by identifying concrete directions for future philosophical and legal research.</p>
